deal with .lng files in test suite?
When we imported iso test data from libosinfo to osinfo-db, we brought some .lng files with it, such as:
$ cat ./tests/isodata/win/win7/en_windows_7_enterprise_n_with_sp1_x64_dvd_u_677704.iso.lng [general] l10n-language=en_US
But the test suite doesn't do anything with them. I think libosinfo's test suite did something with them at one point. We should consider replicating it, or perhaps moving some of the data back to libosinfo and revive the tests there.
