Colima using global tmp preventing vm start-up in multi user usage when using --vm-type=vz

### Description

Colima has problems with using `/tmp/colima` or `/tmp/colima-` when used in a multi user context
Specifically when 2 users run `colima start` separately one users container will not be able to access `/tmp/colima` as that folder is owned by another user. When the `vm-type` is `qemu` this error is ignored and colima continues with the `--very-verbose` log containing this:
```
> [hostagent] The essential requirement 4 of 4 is satisfied
> [hostagent] Mounting "/Users/" on "/Users/"
> [hostagent] Mounting "/tmp/colima" on "/tmp/colima"
> [hostagent] chdir to "/tmp/colima" failed: Permission denied
> [hostagent] Waiting for the guest agent to be running
```

When the `vm-type` is `vz` this creates a full exception with an error line of:
```
{"level":"fatal","msg":"Error Domain=VZErrorDomain Code=2 Description=\"Invalid virtual machine configuration. A directory sharing device configuration is invalid.\" UserInfo={\n NSLocalizedFailure = \"Invalid virtual machine configuration.\";\n NSLocalizedFailureReason = \"A directory sharing device configuration is invalid.\";\n NSUnderlyingError = \"Error Domain=NSPOSIXErrorDomain Code=13 \\\"Permission denied\\\"\";\n}","time":"2024-02-27T15:25:16+13:00"}
```
and fails to start up

---
This seems to only happen when the `/tmp/colima` dir is initially created by `--vm-type=vz` where the dir has `rwxr-x---` (750) perms vs `rwxr-xr-x` (755) perms when created by `--vm-type=qemu` as `--vm-type=vz` in other logins can still use that dir.

### Output of `colima status`

colima doesn't start running on vz. All examples were run with `--network-address`
It appears to be a non-problem with qemu as I successfully ran the `hello-world` docker image with the permission denied.

### Reproduction Steps

Start from clean state. Delete the `/tmp/colima*` dirs

1. run `colima start --vm-type=vz` in userA
2. run `colima stop` in userA
3. log in to userB
4. run `colima start --vm-type=vz` in userB

outcome: colima fails to run with an error of
```
{"level":"fatal","msg":"Error Domain=VZErrorDomain Code=2 Description=\"Invalid virtual machine configuration. A directory sharing device configuration is invalid.\" UserInfo={\n NSLocalizedFailure = \"Invalid virtual machine configuration.\";\n NSLocalizedFailureReason = \"A directory sharing device configuration is invalid.\";\n NSUnderlyingError = \"Error Domain=NSPOSIXErrorDomain Code=13 \\\"Permission denied\\\"\";\n}","time":"2024-02-27T15:25:16+13:00"}
```
in the ha_stderr.log

the /tmp/colima folder will have permissions of `userA wheel rwxr-x---`

Start from clean state. Delete the `/tmp/colima*` dirs

1. run `colima start --vm-type=qemu` in userA
2. run `colima stop` in userA
3. log in to userB
4. run `colima start --vm-type=vz` in userB
outcome: colima runs correctly and can run the hello-world docker image

the /tmp/colima folder will have permissions of `userA wheel rwxr-xr-x`

### Expected behaviour

Colima should handle the /tmp/colima* directories being owned by other users and be able to start up the container regardless.

### Additional context

I have only tested this on Mac M1 Sonoma.
I have installed colima using nix flakes
