Mark test in optimization-remark.f90 as UNSUPPORTED on RISC-V (#157036)

Make the test more tolerant (needed for RISC-V, as this target is not
expected to emit optimization remarks)

 ! With plain -Rpass, -Rpass-missed or -Rpass-analysis, we expect remarks related to 2 opportunities (loop vectorisation / loop delete and load hoisting).
 ! Once we start filtering, this is reduced to 1 one of the loop passes.
