new: fonts/nerd-fonts/nerdfontssymbolsonly

I thought I would share this with anyone who might be interested. I
notice that there are a few of the patched "Nerd Fonts" already in
ports, but there are some programs (like x11/kitty) which can pick up
symbols automagically from this font without requiring patched fonts.

I've been using this for the past couple of days and, while not perfect,
works well enough.

Diff for nerd-fonts/Makefile is below, tarball for
nerd-fonts/nerdfontssymbolsonly is attached.
