better SITE_PYPI

Primary storage for pypi distfiles is at a URL embedding a hash,
but this is inconvenient for packages, so we're using an alternative
via a redirector to make this easier.

Currently we're using pypi.io, but there are some problems:

- it doesn't seem to be officially recommended
cf https://docs.pypi.org/api/#integration-guide "Predictable URLs"

- it results in a chain of redirects, across 3 domains and 2 TLDs:
Redirected to https://pypi.org/packages/source/s/setuptools/setuptools-75.6.0.tar.gz
Redirected to https://files.pythonhosted.org/packages/source/s/setuptools/setuptools-75.6.0.tar.gz
Redirected to https://files.pythonhosted.org/packages/43/54/292f26c208734e9a7f067aea4a7e282c080750c4546559b58e2e45413ca0/setuptools-75.6.0.tar.gz

- .io is pretty distasteful, considering the history
https://en.wikipedia.org/wiki/Expulsion_of_the_Chagossians etc

The recommended redirector using URLs of the form
https://files.pythonhosted.org/packages/source/a/abc/abc-123.tar.gz
only has a single redirect, and it's in the same domain as the original
request, so more efficient all round.

Changing the location for port fetches is straightforward, but portroach
will need a tweak to cope too.

Antoine, if I commit the portroach bit first, how long should I wait
before committing network.conf?

OK?
