dev-python/mypy: add missing build dependencies for native-extensions

It has to run mypy at build time, so all RDEPEND must also be BDEPEND
here. I thought I had originally added this...

This prevents building with e.g. different root or --buildpkgonly, where
RDEPEND isn't used at all (as an implementation detail, building and
installing will merge RDEPEND first, so people might not notice the
issue).
