Let sysui integration tests run in presubmit.

TEST_MAPPING doesn't allow arbitrary intersection of annotations, so
this changes how we label sysui @Scenario tests slightly:

Before:

@Ignore / @FlakyTest: doesn't run at all.
@Staging: runs in staged-postsubmit only.
else: runs in postsubmit (and staged-postsubmit).

After:

@Ignore / @FlakyTest: doesn't run at all.
@Staging: runs in staged-postsubmit only.
@Postsubmit: runs in postsubmit (and staged-postsubmit) only.
else: runs in presubmit (and postsubmit and staged-postsubmit).

The upshot of this is that new tests will need to be marked @Staging or
@Postsubmit until they're known not to be flaky, or presubmit will break
a lot.
