dbus-glib: add support for install regression tests

dbus-glib.inc: default turn off unit test as libdbus-glib-1.so.2.2.2 will
have unit test code if DBUS_BUILD_TESTS enabled. User can turn it on with
PACKAGECONFIG_pn-dbus-glib = "tests" in local.conf or
PACKAGECONFIG ??= "tests" in recipe itself.

Add tests and tests-dbg package.
