util/scripts/update_submodules: Fix branch name greping 

The command "git branch -a | grep -q ${branch}" may not exit with 0 when
pipefail is set. "grep -q" exits immediately with exit code 0 as soon as
a match is found. However, at that point "git branch -a" may be still
writing to the pipe, leading to SIGPIPE. When pipefail is set,
PIPESTATUS 141 will be returned. Fix the problem by not using "grep -q".

Also fix the branch name in the generated commit subject.
