testsuite: Adjust vect-reduc-chain-1.c for SLP permute transform

Since r16-3847-g21d1bb1922f (Integrate SLP permute transform into
vect_transform_stmt), vect-reduc-chain-1.c was failing on aarch64
because the dump message changed.

Apply the same change as r16-3847-g21d1bb1922f applied to
vect-reduc-chain-2.c and vect-reduc-chain-3.c

gcc/testsuite/ChangeLog:

	* gcc.dg/vect/vect-reduc-chain-1.c: Adjust expected
	dump.
