[test] Add more flags to mjsunit/deopt-array-builtin

In this test we expect that the feedback vector is not flushed
so we retain what we have learnt from the earlier executions. If we
flush the earlier feedback the code might deoptimize again and the test
fails. Hence adding --no-stress-flush-bytecode and --no-flush-bytecode
flags.
