Jeremy Huddleston Sequoia 165d5c1260 os: Update GetLocalClientCreds to prefer getpeerucred() or SO_PEERCRED over getpeereid() 
GetLocalClientCreds() was preferring getpeereid() above other implementations.

getpeereid(), however, only returns the effective uid and gid of the peer,
leaving the pid unset.  When this happens, we are unable to use the pid to
determine the peer's command line arguments and incorrectly treat ssh-tunneled
traffic as local.

To address this, we now prioritize getpeerucred() or SO_PEERCRED as those two
implementations will return the pid in addition to uid and gid.
