Add an environment variable to Virtual Me2Me session.

Add an environment variable to Virtual Me2Me session.

This allows users to write session startup scripts (~/.xsessionrc etc) with
parts that are conditional on a Virtual Me2Me session, for example:

if [ -n "$REMOTING_ME2ME" ]; then
  do stuff only in a ME2ME virtual session
fi

lgtm with a couple of suggestions.

http://codereview.chromium.org/9385023/diff/1/remoting/tools/me2me_virtual_ho...
File remoting/tools/me2me_virtual_host.py (right):

http://codereview.chromium.org/9385023/diff/1/remoting/tools/me2me_virtual_ho...
remoting/tools/me2me_virtual_host.py:292: "REMOTING_ME2ME": "y" }
Nit: Wouldn't "1" be a better value to set it to?

Also, I'd suggest REMOTING_ME2ME_SESSION, so that REMOTING_ME2ME_ can be a
standard prefix to "namespace" any other variables we might want to set.
