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 changes add the necessary environment (the currently idiomatic way
to solve such problems) to the existing wrapper.
The use in `preFixup` is necessary, as the gapps wrapper will not have
ran the required hooks before.
The addition of `gobject-introspection` is necessary for the wrappers
hooks to add GIR repositories to the wrapper args.
