python-numpy: Avoid installing copy of f2py script

Both python-numpy and python3-numpy try to install the file:

${D}/${bindir}/f2py

which causes an error during do_rootfs since the package manager complains about that.

The numpy packages create basically copies of f2py script with the following names:
f2py (on both)
f2py2 (on python 2)
f2py2.7 (on python 2)
f2py3 (on python 3)
f2py3.7 (on python 3)

Remove the copy of f2py from python-numpy in favor of using the one from python3
to avoid installation issues at do_rootfs().
