mjit.c: define __EXTENSIONS__ earlier

Another try of r62204 and r62192.

As far as I can see from solaris's signal.h and sys/procset.h, the only
possibility that causes the following error would be that sys/procset.h
is included without __EXTENSIONS__ and signal.h included it again but it
doesn't define procset_t.  Let's define __EXTENSIONS__ from first.
