If seunshare uses PR_SET_NO_NEW_PRIVS, which certain versions of
libcap-ng set, setexeccon will cause execve to fail. This also
makes setting selinux context the very last action taken by
seunshare prior to exec, as it may otherwise cause things to fail.
Note that this won't work without adjusting the system policy to
allow this use of setcurrent. This rule appears to work:
allow unconfined_t sandbox_t:process dyntransition;
although a better rule would probably relax the unconfined_t
restriction.
