new uidmap BATS test: fix

Various problems, one of which was causing the test to fail
completely (otherwise I wouldn't have caught the others):

- option is --uidmap, not --uidmapping
- run_podman cannot be piped (| grep /sys/kernel). That's
  an unfortunate limitation of BATS. Any invocation of 'run'
  saves results to $output, which then has to be tested
  in a separate step.
  - do so, using 'run' and 'grep' and 'is' to produce
    readable messages on failure
- remove "$expected_rc", that looks like a copy/paste bug
  from a few lines above.

Skip entire test if rootless. (The one without --net=host
passes, but it also passes with older podman as both root
and rootless. I don't think it's actually testing anything,
but agree with leaving it in to catch weird regressions).

We really need to get these tests running in CI.
