Add snakemake to python3 builds

[thomas]

It won't hurt to have a 'versionend' snakemake within the python3 context, whilst also keeping the standalone variant.

When you've built python-3.7.1-1 you already seem to have readded snakemake. And I don't understand 'versionend' snakemake. Can this issue been closed?

snakemake is now part of python-3.7.3-0, see #60.
