util/scripts: extend cross-repo-cherrypick 

The script now automatically discovers the original branch (if known)
and configures itself appropriately.
Additionally, commit messages for changes coming _from_ upstream will
be prefixed with "UPSTREAM: ".
With the optional --cros argument, it also adds a BUG/BRANCH/TEST block
at the right place in the commit message (right above the metadata) if
one doesn't already exist.
