[PATCH v2] t4253-am-keep-cr-dos: avoid using pipes




The exit code of the upstream in a pipe is ignored thus we should avoid
using it. By writing out the output of the git command to a file, we can
test the exit codes of both the commands.

Thanks to Eric Sunshine's review, I've removed spaces after '>'
and changed 'actual' into 'output'.
