[Buildroot] [git commit] download/git: don't require too-recent git

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=e17719264b5df0400442f02366cc16201ab3a25c
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

git has supported -C only since 1.8.5, and some distros have not yet
caught up after more than 4 years...

Fall back to entering the directory.

Fixes:
