Update the ctags rules and targets.

As there’s no C++ runtime any more there’s really no point in having
anything but Rust tags being made.

I’ve also taken the liberty of excluding the compiler parts of this in
the `librust%,,` pattern substitution. Whether or not this is “correct”
will depend on whether you want tags for the compiler or for general
use. For myself, I want it for general use.

I’m not sure how much people use the tags files anyway. I definitely do,
but with Racer existing the tags files aren’t quite so necessary.
