libsexy: remove

People have only been using this for the spell-entry widget, i.e even
hexchat just has the code vendored and are maintaining it themselves.

There is a continuation that could be packaged if anyone needs it
* https://github.com/TingPing/libsexy3
but currently no package within nixpkgs has a use for this.
