[GIT PULL] Security subsystem: general updates for v4.18

[James Morris]

Please pull these general security subsystem updates for v4.18.

Summary:

- Incorporate new socketpair() hook into LSM and wire up the SELinux and 
  Smack modules.  From David Herrmann:

   "The idea is to allow SO_PEERSEC to be called on AF_UNIX sockets 
    created via socketpair(2), and return the same information as if you 
    emulated socketpair(2) via a temporary listener socket. Right now 
    SO_PEERSEC will return the unlabeled credentials for a socketpair, 
    rather than the actual credentials of the creating process."

- Sargun Dhillon removed the unused security_settime LSM hook.

- Tycho Andersen removed some stack allocated arrays from the keys code.
