limactl not in path after installation

### Description

I build the project from source in Ubuntu. After `sudo make install` I tried to run colima and got an error stating that limactl was no in the path. At this point I don't even know if it is in my system.

I expect the build system to check that (do I have that dependency) otherwise the README should have it. If I don't have limactl, I assume it should be installed by the build process and its path added to PATH.
By the way, if it supports Linux, the main README should have instructions on how to install in Linux (apt get?).

### Version

Latest at the time of writing.

### Operating System

### Output of `colima status`

### Reproduction Steps

### Expected behaviour

After `sudo make install` I should be able to run `colima` without problems.

### Additional context

Prüfe im Makefile das install-Ziel, um zu sehen, wie Abhängigkeiten behandelt werden. Sieh im README nach vorhandenen Installationsanweisungen, insbesondere für Linux. In diesem Issue geht es darum sicherzustellen, dass sich limactl im PATH befindet oder als Voraussetzung dokumentiert ist; prüfe, ob der Build-Prozess dies überprüft oder limactl installiert.
