install_linux_packages: Add fallback to identify known distro. 

Python versions before 3.10 did not have the
`platform.freedesktop_os_release` utils, use the trick based on looking
for distro-specific version files instead as fall-back (same as what was
done in the previous `install_deps.sh` bash script).
