[PATCH] S390: Fix sem.h conformance test failures.

[Stefan Liebler]

Hi,

on s390 the following tests are failing:
FAIL: conform/UNIX98/sys/sem.h/conform
FAIL: conform/XOPEN2K/sys/sem.h/conform
FAIL: conform/XOPEN2K8/sys/sem.h/conform
FAIL: conform/XPG3/sys/sem.h/conform
FAIL: conform/XPG4/sys/sem.h/conform

The test out files report:
...

     Member "sem_otime" does not have the correct type.  Compiler message:

This patch changes the s390 specific sem.h and includes sys/types.h 
instead of bits/types.h. All other archs include sys/types.h, too.
Including bits/wordsize.h is obselete, because it is already inlcuded in 
sys/types.h -> bits/types.h.

The conformance tests are passing now on s390/s390x.

Ok for commit?

Bye
Stefan
