dev-python/pypy: Bump to 7.0.0

Bump to the new 7.0.0 release, and update CPython patchset.  Upstream
has apparently started using /usr/lib/pypy2.7 as package location
independently of prefix, so our patches stopped being necessary (but we
need subslot bump to move everything).  Thanks to Sander Sweers
for the early notification and research on the new release.

Bug: https://bugs.gentoo.org/677398
