repo: standardize help behavior

Standard utilities exit normally/zero when users explicitly request
--help, and they write to stdout.  Exiting non-zero & using stderr
is meant for incorrect tool usage instead.  We're already doing this
for `repo help <init|gitc-init>` calls, so lets fix `repo help` and
`repo --help|-h` to match.
