test: Export G_TEST_BUILDDIR, G_TEST_SRCDIR

Browse source 
These environment variables are used by GLib's g_test_build_filename()
and related convenience functions, which make it easier for unit tests
to find data files in a way that works for both build-time tests and
"as-installed" tests. During "as-installed" testing, both variables
will normally be unset, and GLib uses the directory containing the
executable. In most cases that results in the right thing happening, and
this will also be true for dbus, since we install the test executables
in ${libexecdir}/installed-tests, helper executables in the same place,
and test data in ${libexecdir}/installed-tests/data.
