s390: testsuite: Fix autovec-double-signaling-eq-z13.c

Since r15-3992-g698e0ec89bc096 we optimize x<=y && x>=y to x==y.
Honour signaling NaNs by using option -fsignaling-nans in order to
prevent this.

gcc/testsuite/ChangeLog:

	* gcc.target/s390/zvector/autovec-double-signaling-eq-z13.c:
	Honour sNaNs.
