AK2: more multi-partition support improvements

- check for and remove patch for multi-partition/reset_ak (so removal of ramdisk/ and patch/ with the addition of $(basename block)-files is now the full trigger)
- wipe $(basename block)-files/ramdisk to ensure proper copied output, as the original contents are retained in the copied rdtmp
- for ramdisk-only changes that don't require added files or patch snippets, create the $(basename block)-files subfolder for proper output backup with reset_ak
