[OE-core] [PATCH v2] createrepo-c: Fix setup of logging (log domains)

[Zheng Ruoqin]

New debug messages were added into GLib library. These messages come
from the "GLib" log domain and were not hidden in the standard and
quiet mode of the application.
This fix hides log messages regardless on source log domain.

Backport from 80810f04f2de6bae6e394f52ad9cdd2189862f74.
