This can be run when installed or uninstalled. When uninstalled, it
requires G_TEST_BUILDDIR and G_TEST_SRCDIR to be set.
The idea with this test harness is to test the glib-genmarshal utility, its
handling of command line arguments, its exit statuses, and its handling of
various marshaller lists. In future we could split the core glib-genmarshal
parsing and generation code out into a library and unit test that, and
convert this test to just check command line behaviour.
