src: ogChangeRepo returns zero on success and -1 on error

do not return the returncode, instead return an integer.

do not use

	except CalledProcessError as e:

it causes a another exception while handling exception.

Remount the original image repository.

it should be possible to simplify this further by:

- stacking mounts, no need to umount initial repo and mount it again
  when switching to the new repo, because remount back initial repo
  might fail (!)

- use check=False and simply check for x.returncode
