Move a pair of gobject tests to tests/gobject/

testgobject.c and timeloop-closure.c are the only two tests in the
toplevel tests/ directory that depend on gobject, so move them to
tests/gobject/ along with the other gobject tests.

Both of these were in noinst_PROGRAMS and not TESTS, so keep them that
way when we move them.
