meson: Check for os-release's ID_LIKE in addition to ID

meson: Check for os-release's ID_LIKE in addition to ID

This makes it possible to reduce the number of cases we have to
consider, because 'sles' declares itself to be like 'suse' and
both 'rhel' and 'centos' declare themselves to be like 'fedora'.

We have to move the check for Ubuntu before the one for Debian,
however, because 'ubuntu' declares itself to be like 'debian'
and it would end up with the wrong defaults otherwise.
