Fix the gn wrapper to be aware of the --root argument.
The gn binary itself is capable of being run from outside of a
checkout as long as you pass the --root flag.
However, the gn.py wrapper script needs to *also* know where the the
checkout is, in order to figure out how to find the gn binary itself.
This patch changes the wrapper to be aware of the --root arg :).
