Title: Bug 854121:  Regenerate sources.xml unconditionally rather than only when the underlying manifest changes

It is quite common for the revisions underlying the build to change without the manifest changing, for example, when "./repo sync" pulls a few new gecko or gaia revisions. This change makes us regenerate sources.xml in those cases.
