security/sudo: update to 1.8.31p2

Update sudo package to 1.8.31p2.

What's new in Sudo 1.8.31p2

 * Sudo command line options that take a value may only be specified
   once.  This is to help guard against problems caused by poorly
   written scripts that invoke sudo with user-controlled input.
   Bug #924.

 * When running a command in a pty, sudo will no longer try to
   suspend itself if the user's tty has been revoked (for instance
   when the parent ssh daemon is killed).  This fixes a bug where
   sudo would continuously suspend the command (which would succeed),
   then suspend itself (which would fail due to the missing tty)
   and then resume the command.

 * If sudo's event loop fails due to the tty being revoked, remove
   the user's tty events and restart the event loop (once).  This
   fixes a problem when running "sudo reboot" in a pty on some
   systems.  When the event loop exited unexpectedly, sudo would
   kill the command running in the pty, which in the case of "reboot",
   could lead to the system being in a half-rebooted state.

 * Fixed a regression introduced in sudo 1.8.23 in the LDAP and
   SSSD back-ends where a missing sudoHost attribute was treated
   as an "ALL" wildcard value.  A sudoRole with no sudoHost attribute
   is now ignored as it was prior to version 1.8.23.
