[meta-oe][PATCH 3/5] nodejs: allow use of system gyp

["André Draszik" <git@andred.net>]

Now that there is a gyp (python2) recipe in meta-python,
allow its use instead of the bundled one for when
meta-python is enabled.

At the same time, unconditionally inherit pythonnative
as in either case gyp actually uses python, and the
build machine's python and installed modules should
never be used.
