configure: restore check for glib libraries

This is a partial revert of 2375607039517c88df. We still have code
guarded by HAVE_GLIB in tests.

v2:
- do not define the automake conditional, it wasn't used anywhere
- rename --disable-gudev to --disable-glib

v3:
- do not cause an error if the libs are not found, this is supposed
  to be an "auto" dep by default.
