Set the preserve argv0 flag for Rosetta installations on macOS > 13

### Description

The current rosetta binfmt_misc code does not set the preserve argv0 (`P`) flag when registering the binfmt handler. This flag is supported since macOS 14, and Apple even [recommends it in their documentation](https://developer.apple.com/documentation/virtualization/running-intel-binaries-in-linux-vms-with-rosetta#Mount-the-Shared-Directory-and-Register-Rosetta).

This means that programs that look at their own `argv[0]` will get the actual path that they were called by, instead of the full resolved path that Rosetta would otherwise provide. This fixes some subtle bugs in programs such as `clang` that look at the path by which they were called to resolve sysroots.

This is a fairly trivial thing to implement, since the set up code only needs to check the macOS version and if it's above 13 it can add the 'P' flag.
