Add test data for tests/runtestfedabipkgdiff.py

While applying the patch 59917a8 and resolving the conflicts that
arose then, I forgot to git add the RPMs that were needed by the
accompanying test.

This test fixes that.

	* tests/data/test-fedabipkgdiff/dbus-glib-0.104-3.fc23.x86_64.rpm:
	New file.
	* tests/data/test-fedabipkgdiff/dbus-glib-0.80-3.fc12.x86_64.rpm: Likewise.
	* tests/data/test-fedabipkgdiff/dbus-glib-debuginfo-0.104-3.fc23.x86_64.rpm:
	Likewise.
	* tests/data/test-fedabipkgdiff/dbus-glib-debuginfo-0.80-3.fc12.x86_64.rpm:
	Likewise.
