[testsuite] [riscv] xfail some [PR113281] tests

Some of the tests regressed with a fix for the vectorization of
shifts.  The riscv cost models need to be adjusted to avoid the
unprofitable optimization.  The failure of these tests has been known
since 2024-03-13, without a forthcoming fix, so I suggest we consider
it expected by now.  Adjust the tests to reflect that expectation.
