[PATCH v2] pypi: set SRC_URI with _prepend, not with +=

This did not cause problems in builds, but broke some devtool
workflows such as version upgrades or checking the latest version
from upstream. Tarballs should come first, not the patches.

FYI this breaks podman-compose in meta-virtualization which was setting own
git:// SRC_URI after pypi inherit and now both entries end in SRC_URI and
fetch fails with:

ERROR: podman-compose-0.1.5-r0 do_fetch: No checksum specified for
'/OE/build/oe-core/downloads/podman-compose-0.1.5.tar.gz', please add at
least one to the recipe:
SRC_URI[sha256sum] =

Missing SRC_URI checksum

I'll send fix for Bruce.
