Merge branch 'jk/repack-silence-auto-bitmap-warning'

Browse Source 
Squelch unneeded and misleading warnings from "repack" when the
command attempts to generate pack bitmaps without explicitly asked
for by the user.

* jk/repack-silence-auto-bitmap-warning:
  repack: simplify handling of auto-bitmaps and .keep files
  repack: silence warnings when auto-enabled bitmaps cannot be built
  t7700: clean up .keep file in bitmap-writing test
