payloads/external/GRUB2: fix constantly rebuilding due to git checkout
Multiple git checkouts cause GRUB2 to constantly rebuild even if there
were no changes to code or config. This is due to changing timestamps.
Fix this by not creating or switching branches but instead rely on
`git checkout -f` which does not touch existing unchanged files.
To be sure to not break anyones workflow checkout is skipped and a
warning gets printed if the tree/index is unclean.
