Update git submodules

* Update docs/submodules/oom/offline-installer.git from branch 'master'
  to 0c3aeee286896377c3464dfea54364ccd0807ca8
  - Merge "Add directory remove on failed cloning"
  - Add directory remove on failed cloning

    While downloading git repositories there was no removing
    of created destination directory which could led to false
    detection of downloaded repository.

    This script adds directory remove in such case plus fixes
    some minor typos in logging and help strings.
