Convert loader to use GIO

Direct use of POSIX/stdc I/O is deprecated in favour of
the GIO system. Re-write the OsinfoLoader to use GIO
for loading XML from arbitrary paths/uris.

* configure.ac: Check for GIO library
* osinfo/Makefile.am: Link to GIO
* osinfo/osinfo_loader.c, osinfo/osinfo_loader.h: Port
  to GIO
* test/osinfo.suppression: Supress many GIO data types
* test/test-loader.c: update for new GIO api.
