Removing FRidh as active maintainer of packages

In the past I was very active with Python packaging.
For several years now I was hardly around as maintainer,
so it does not make sense I am listed as a maintainer for
these makes. Looking back, I should have removed myself
as maintainer already much longer ago. Anyway, better late
than never.

It's been a fun ride, and  I do intend to occasionally contribute
to Nixpkgs, but not in the same way it once was.
