When submitting, git-p4 finds the current branch in
order to know if it is allowed to submit (configuration
"git-p4.allowSubmit").
On a detached head, detecting the branch would fail, and
git-p4 would report a cryptic error.
This change teaches git-p4 to recognise a detached head and
submit successfully.
