Improve check_all_upgrades.sh

- Report target version when testing upgrades from unpackaged to :auto
 - Fix handling all specific-version parameter followed by exclamation mark
 - Check availability of unpackaged upgrade file
 - Report extension in PASS/FAIL messages

NOTE: this makes dronie really test upgrades via function, which
      was NOT really working as of 8c741465d
