osdep: Remove local definition of macro offsetof
The macro offsetof is defined in stddef.h. It is conforming to
the standards C89, C99 and POSIX.1-2001 (see man page), so it
is a sufficiently old standard.
Therefore chances are very high that QEMU never needs a local
definition of this macro.
osdep.h already includes stddef.h, so this patch simply removes
the unneeded code from the files configure and osdep.h.
If we ever need the local definition again, it should be added
to compiler.h (the macro is usually provided with the compiler,
it is not OS specific).
