The nixpkgs-unstable channel's programs.sqlite was used to identify
packages producing exactly one binary, and these automatically added
to their package definitions wherever possible.
These are all packages that I stopped using and hence just create noise
in my inbox for each change affecting them and let's face it, while I
still enjoy contributing to nixpkgs, it doesn't really make sense to be
listed there if I can't do much anyways.
Each of these packages can be taken over by someone or removed if
people think that's reasonable.
Of course, if other maintainers face issues, I can answer some questions
if needed & possible.
Update to the latest revision, don't replace `which` anymore as all
`which` references are eliminated previously, enable support for at
least one database type (otherwise this scrpit is unusable and needs to
be built manually with support for on of these packages).
Tested functionality with a simple SQLite database.
