git-remote-entire: unify git protocol agent and HTTP User-Agent

The previous commit stamped the HTTP User-Agent with versioninfo.Version
while the git protocol agent kept its prior versioninfo.Commit format,
leaving two different identifiers for the same binary. Use the
version-stamped form for both — server-side log analysis can correlate
git protocol agent and HTTP access-log entries without translation, and
the conventional binary/version shape matches what the rest of the
entire HTTP clients advertise.
