pypy27: 7.3.9 -> 7.3.11

Also build it with pythonInterpreters.pypy27_prebuilt instead of
python27, to avoid it being broken after #201859 is merged.

Keep in mind that the above change will make this derivation only work
with x86_64-linux for now (since pypy27_prebuilt is only packaged for
that platform). However support for newer platforms can be added later,
and a working package for one platform is better than a broken package
in 4 platforms.
