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.
This removes the spidermonkey alias and renames it in the packages still
using it
Not sure if we need it in aliases.nix since just about nothing depends
on it anymore
Additionally considering removal should be a good choice, it's at least
insecure so it should get tagged as such
