testsuite/vec: Fix vect-reduc-cond-[12].c for non vect_condition targets [PR121153]

I missed this when I added the two testcase vect-reduc-cond-[12].c. These testcases
require support of vectorization of `a ? b : c` which some targets (e.g. sparc) does
not support.

Pushed as obvious after a quick test.

	PR testsuite/121153
gcc/testsuite/ChangeLog:

	* gcc.dg/vect/vect-reduc-cond-1.c: Require vect_condition.
	* gcc.dg/vect/vect-reduc-cond-2.c: Likewise.
