package/nodejs: force the use of python2

Remove the patches to use a python variable and instead force python2
into the PATH.

Upstream the python variable was recently removed
(see https://github.com/nodejs/node/commit/c3e50ca) and due to dependencies
directly calling python there is a reluctance to change this.  Instead it
is recommended to add python2 into PATH as the nodejs build machines do
(see https://github.com/nodejs/node/issues/418 and
https://github.com/nodejs/node/issues/2735).

-Use a python variable instead of hardcoding Python

-The nodejs build system uses python in a number of locations. However,
-there are some locations where it hardcodes 'python' as the Python
-interpreter. However, this causes problems when we need to use python2
-instead of just python.
-
-This patch fixes that by using the python variable already in place in
