USES=luajit

Hello everyone,

I've added Uses/luajit.mk, which supports luajit through DEFAULT_VERSIONS.
The default is luajit-devel, though luajit-openresty is another great
option if you prefer it.

One great benefit is getting people off of lang/luajit, which is a version
that people probably shouldn't use.

I have been converting ports to USES=luajit one-by-one, but I could use a
hand. I don't have a good development box right now, so it's a very slow
process for me to build-test things. Any help in converting the remaining
ports is greatly appreciated!
