gutils test: Don't assume that every Unix OS implements os-release(5)

Browse Source 
os-release(5) is widely implemented on Linux, but not necessarily
ubiquitous: unusual or minimal Linux distributions might not have it.
It could in principle be implemented by any other Unix OS, but in
practice this has not yet happened.

Closes: https://gitlab.gnome.org/GNOME/glib/issues/1906
Fixes: 349318e8 "gutils: Add g_get_os_info()"
