[Buildroot] [PATCH 5/7 v5] download/git: ensure we checkout to a clean state

Force the checkout to ignore and throw away any local changes. This
allows recovering from a previous partial checkout (e.g. killed by
the user, or by a CI job...)

git checkout -f has been supported since the inception of git, so we
can use it without any second thought.

Also do a forced-forced clean, to really get rid of all untracked stuff.
