setup: Reuse golang.pyx.build to build DSOs

We already reuse golang.pyx.build in setup.py to build Extensions, but
DSOs were built via setuptools_dso directly so far. To support Windows
we will soon need to adjust compilation flags for both Extensions and
DSOs. It makes sense to first concentrate build recipes in one place
before doing that.

-> Move/factor DSOs build flags into golang.pyx.build and reuse that
from setup.
