[PATCH 05/19] t5516: drop unnecessary subshell and command invocation

To create its "expect" file, this test pipes into `sort` the output of
`git for-each-ref` and a copy of that same output but with a minor
textual transformation applied. To do so, it employs a subshell and
commands `cat` and `sed` even though the same result can be accomplished
by `sed` alone (without a subshell).
