Take user namespaces into account in policy checks
Change file related checks to use user namespaces and make
sure involved uids/gids are mappable in the current
namespace.
Note that checks without file ownership information will
still not take user namespaces into account, as some of
these should be handled via 'zfs allow' (otherwise root in a
user namespace could issue commands such as `zpool export`).
This also adds an initial user namespace regression test
for the setgid bit loss, with a user_ns_exec helper usable
in further tests.
Additionally, configure checks for the required user
namespace related features are added for:
* ns_capable
* kuid/kgid_has_mapping()
* user_ns in cred_t
