os-release: define /usr/lib/os-release as fallback for /etc/os-release
The file should have been in /usr/lib/ in the first place, since it describes the OS container in /usr (and not the configuration in /etc), hence, let's support os-release files in /usr/lib as fallback if no version in /etc exists, following the usual override logic. A prior commit already enabled tmpfiles to create /etc/os-release as a symlink to /usr/lib/os-release should it be missing, thus providing nice compatibility with applications only checking in /etc. While it's probably a good idea if all apps check both locations via a fallback logic, it is only necessary in the early boot process, as long as the /etc/os-release symlink has not been restored, in case we boot with an empty /etc.
