Wattributes.c testcase: Disable warning check for IBM Z.

On IBM Z we enforce function alignment to 8 bytes.  Hence we get an
error instead of a warning when trying to specify smaller alignments.

gcc/testsuite/ChangeLog:

2018-04-06  Andreas Krebbel  <krebbel@linux.vnet.ibm.com>

	* c-c++-common/Wattributes.c: Disable warning for s390* target and
	check for an error instead.
	* gcc.dg/Wattributes-6.c: Likewise.
