[Buildroot] [PATCH 3/6 v2] download/git: ensure we checkout to a clean state

[Yann E. MORIN]

Force the checkout to ignore 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.
