Migrate universal-ctags setup to home-manager

As we add more and more files, move to set with curly braces.
Maybe home-files is a better approach, but not documented and I don't
understand it to well yet. I guess I've to create a derivation which
"builds" all the files. Maybe to complicated right now.

Might also make sense to build modules for such tools in future where I
can configure within nix, just like git.nix, and it will generate the
config. Might be cool for some things where configs might change, but
the actual things to configure might not. The generation of the file can
change within nix, while configuration within nix stays the same?! ;)
