ignore python folder included within hackable hg packages

the exewrapper.c that builds hg.exe for the hackable hg packages allows two
names for the Python install folder, hg-python or python2N where N matches the
minor version of Python you compiled against.

the hg-python/ path is only checked when PYTHONHOME is found in the environment,
for reasons that are just beyond my comprehension. So it is easier for me to
just use python27/ for my hackable-hg packages but this path is not yet ignored.
