recipes: update for PYPI_PACKAGE change

The pypi class has slightly changed the semantics of the PYPI_PACKAGE
variable[1], now PYPI_PACKAGE is the normalised package name and the new
variable PYPI_PACKAGE_SDIST is used when the source tarball doesn't match.

Update recipes as appropriate: this is mostly deleting now-redundant
assignments but some assignments are still needed where packages are not
uploaded using the modern standards.
