[COMMIT/RFC] Always include <sys/types.h> from defs.h

[Mark Kettenis <mark.kettenis@xs4all.nl>]

Including <sys/types.h> is a prerequisite to including many of the
other <sys/...> header files on BSD-derived systems.  Since it isn't
the case on Linux, evry now and then the build is broken when someone
developing on Linux adds <sys/whetever.h>.  This patch prevents this
from happening ever again.

Committed as obvious, since this is what bfd/sysdep.h and
opcodes/sysdep.h already do.  Makes GDB build on vax-dec-ultrix4.0
again ;-).

Raises the question whether we should move towards eliminating
<sys/types.h> from all other GDB source files.  What do folks think
about that?
