Allows building nodejs in Arch Linux without a virtualenv.

As Arch Linux uses python3 as default, gp.recipe.node cannot build
nodejs without being inside a virtualenv. However, thanks to some PATH
manipulation, Nodejs can now be built outside a virtualenv when the
default python is Python3. This should simplify project setup back to a
simple "python bootstrap.py".
