[GSoC PATCH 02/16] t6423: avoid suppressing git's exit code

[Trieu Huynh <vikingtc4@gmail.com>]

Update t6423-merge-rename-directories.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.
