[tracker-miners] extract/gstreamer: blacklist via plugin rather than feature

[Robert McQueen <ramcq src gnome org>]

commit 3560b4606d064d75c7caa8a2e3ad3c69ac0e3345

    extract/gstreamer: blacklist via plugin rather than feature
    
    Using a features-based blacklist means that you need to keep adding
    new blacklist entries when new codecs are added, and makes it impossible
    to match plugins which generate features dynamically based on
    detected hardware.
