  LSM: SafeSetID: Fix warnings reported by test bot (2020-10-13 09:17:36 -0700)

SafeSetID changes for v5.10

The changes in this pull request are mostly contained to within the
SafeSetID LSM, with the exception of a few 1-line changes to change
some ns_capable() calls to ns_capable_setid() -- causing a flag
(CAP_OPT_INSETID) to be set that is examined by SafeSetID code and
nothing else in the kernel. These changes have been baking in -next and
actually were in -next for the entire v5.9 merge window but I didn't
have a chance to send them.

The changes to SafeSetID internally allow for setting up GID transition
security policies, as already existed for UIDs.

NOTE: I'm re-using my safesetid-next branch here as the branch for
creating the pull request. I think that's fine, not sure if this is the
normal workflow or not. Also, I use 'git rebase vX.X' to put my commits
on top of the latest stable release. Again, I verified with gitk that I
don't have any weird history in my branch that will mess things up so
AFAICT that should be fine too.
