testsuite: Fix gcc.dg/vect/pr99102.c command line

The aarch64_sve256_hw line forced the vector length, but didn't force
SVE itself.  This meant that the associated:

  /* { dg-final { scan-tree-dump "MASK_SCATTER_STORE" "vect"  { target aarch64_sve256_hw } } } */

wouldn't always fire.  I imagine this was tested with SVE enabled by
default, which would have masked the problem.

	* gcc.dg/vect/pr99102.c: Force SVE when forcing the vector length.
