am: Fix broken guessbranch handling

b4's usage of git-log '--branches' option is broken. The option takes a
glob pattern *only* and must have an '=', but b4 ends up passing
'--branches <guessbranch>' to git-log. This will kind of work, but is
not checking only 'guessbranch'. For example, these 3 commands all do
something different:

git log -1 --branches=master

git log -1 --branches master

git log -1 --branches=*aster

A maintainer wanting to apply a patch or series likely has a small set of
known branches they apply patches to. Using a glob pattern is not a good
fit for that. Instead, allow --guess-branch to be repeated and to take
fixed refs.
