[libvirt] [PATCH] Be more clever and verbose about localization-initialization.

[Fuchs, Andreas]

Currently libvirt fails with an uninformative error message if no translations are found.

Fixes:
* If bindtextdomain fails due to missing language files, fall back to locale C.
* If textdomain still fails, report the exact error without translation attempt.
