seafile: Remove Python variants, update Python packaging

This removes Python build variants and adds PYTHON3_PKG_BUILD:=0 (where
appropriate) for the Seafile packages.

This also updates the way the Python bindings packages are packaged,
using automake installation instead of manual install recipes.
