regcomp.h: Remove unused #define

ANYOF_RUNTIME() is no longer used, so can be removed.

I had long tried to figure out what the purpose of this was, and
discovered it really had none.

I think it must have had something to do with locales at one time.  But
locales don't do well with utf8, and I don't know how to make it better.
In any event this wasn't actually accomplishing anything.
