repo download: add --ff-only option

Browse Source 
Allows to ff-only a gerrit patch
This patch is necessary to automatically ensure that the patch will
be correctly submitted on ff-only gerrit projects

You can now use:
repo download (--ff-only|-f) project changeid/patchnumber

This is useful to automate verification of fast forward status of a patch
in the context of build automation, and commit gating (e.g. buildbot)
