fontconfig: fix 70-no-bitmaps for deprecation

70-no-bitmaps now includes 70-no-bitmaps-except-emoji, but this only
works if 70-no-bitmaps-except-emoji is already in conf.d (not just
conf.avail). This fixes regressions some users have been reporting with
bitmap fonts showing up again since the latest update.
