Uppity: clear some key environment vars in subprocesses.

Browse Source 
My helper scripts for invoking Uppity have been manually unsetting
things like XAUTHORITY and SSH_AUTH_SOCK, to avoid accidentally
passing them through from my primary login session, so that I don't
get confused about whether agent forwarding is happening, or end up
with one DISPLAY going with a different XAUTHORITY.

Now I clear these within Uppity itself, so the wrapping script won't
have to.
