aarch64: testsuite: disable stack protector for sve-pcs tests

If GCC is configured with --enable-default-ssp, the stack protector can
make many sve-pcs tests fail.

gcc/testsuite/ChangeLog:

	* gcc.target/aarch64/sve/pcs/aarch64-sve-pcs.exp (sve_flags):
	Add -fno-stack-protector.

(cherry picked from commit edb336cc575a82cfc2a883e4c3453c36267482c1)
