Skip individual namespace-type checks that policy disables

Browse Source 
Same class of test gap as the net-namespace test just fixed: this test
filtered which of pid/uts/ipc/cgroup to check by kernel support alone,
never by the config's own policy, so running the full suite as root with
every unshare-* flag forced off (via -c/--config-file) correctly made
bwrap skip requesting all four -- production code working as configured,
not a bug -- while the test still asserted each was isolated and failed.

Reuses namespace_type_would_isolate() (introduced in the previous commit)
to filter to_check by both gates instead of kernel support alone.

Full suite as root with everything disabled: 78 test cases, 76 passed, 2
skipped (this one and the net-namespace test), 0 failed -- the complete
picture requested.
