recipetool: pypi: do not clobber SRC_URI checksums

The pypi change:
"85a2a6f68af recipetool: create_buildsys_python: add pypi support"
deleted all the SRC_URI variables, including the SRC_URI checksums.
These are not generated by the pypi.bbclass (how could they be trusted?)

Without the checksum(s), we are vulnerable to a man-in-the-middle attack
and zero checks on the validity of the downloaded tarball from pypi.org.

Fix by only setting S and SRC_URI to None.
