package/python-numpy: fixup npymath.ini for numpy extensions

Browse Source 
In order to build the numpy distutils extension packages like
python-scipy, python-numba, it requires an explicit pkg-config
path fixup for npymath.ini.

This pkg-config path fixup would update the prefix path of
npymath.ini with actual target staging area where numpy core
was built, so that numpy distutils extension packages would
explicitly link this config path for their package environment.

Without this extension packages cannot find -lnpymath since
it uses host libraries (like libnpymath.a).

So, attach the post install staging hook with pkg-config
path fixup for npymath.ini.
