preproc.c: Turn off rmacro,exitmacro support

We've a problem in supporting [i]rmacro, exitmacro
facilities at moment.

In a sake of not holding new NASM release any longer these
directives are just marked as being "forbidden".

This allow us to not squash much changes in current source
code base but remain on a safe side same time.
