x11/kitty redundant dependency on x11-fonts/nerd-fonts

A recent update (0.42.2) to x11/kitty port has included a new dependency on the x11-fonts/nerd-fonts port, which is massive in used disk space. However nerd font symbols are already bundled with Kitty and the new dependency seems redundant.

From https://sw.kovidgoyal.net/kitty/faq/#kitty-is-not-able-to-use-my-favorite-font
> If you are trying to use a font patched with Nerd Fonts symbols, don't do that as patching destroys fonts. There is no need, kitty has a builtin NERD font and will use it for symbols not found in any other font on your system.
