[aur-general] Merge Request: zeitgeist-dataprovider-firefox => zeitgeist-datasource-firefox

[zeitgeist-dataprovider-firefox][1] is orphaned and obsoleted long ago, it is actually a bzr package but with a unqualified name, and the source is dead. [zeitgeist-datasource-firefox][2] provides the same thing using a released tarball.
