bin/get-{extra,fixes}-pick-list.sh: add support for ignore list

Both scripts does not use a file with the commits to ignore. So if we
have handled one of the suggested commits and decided we won't pick it,
the scripts will continue suggesting them.

v2:
- Mark the candidates in bin/get-extra-pick-list.sh (Juan A. Suarez)
- Use bin/.cherry-ignore to store rejected patches (Emil)
