hook: support a --to-stdin=<path> option
Expose the "path_to_stdin" API added in the preceding commit in the
"git hook run" command.
For now we won't be using this command interface outside of the tests,
but exposing this functionality makes it easier to test the hook
API. The plan is to use this to extend the "sendemail-validate"
hook[1][2].
