t4129: prevent loss of exit code due to the use of pipes

Piping the output of git commands like git-ls-files to another command (grep in this case) hides the exit code returned by these commands. Prevent this by storing the output of git-ls-files to a temporary file and then "grep-ping" from that file. Replace grep with test_grep as the latter is more verbose when it fails.
