[GSoC PATCH 04/16] t6101: avoid suppressing git's exit code

[Trieu Huynh <vikingtc4@gmail.com>]

Update t6101-rev-parse-parents.sh to redirect git-cmds output
to a temporary file instead of piping it directly to not hide
the exit code of git commands behind pipes, as a crash in git
might go unnoticed.
