glib-2.0: upgrade to latest stable, 2.34.1.

glib-2.0: upgrade to latest stable, 2.34.1.

Also explicitly disable the test suite (as we can't run it), subsequently
dropping 60_wait-longer-for-threads-to-die.patch and nodbus.patch.

nolibelf.patch has been merged upstream, drop.

Upstream has dropped the pre-generated man pages, to generate them again we'd
need libxslt and the DocBook infrastructure.  We can live without the man pages
as those build-dependencies are non-trivial.
