Subject: [PATCH 0/2] Landlock: Add abstract unix socket connect reastriction

This patch series introduces the optional scoping of abstract unix
sockets. This feature aims to scope the connection of an abstract socket
from a sandbox process to other sockets outside of the sandbox domain.
(see [1, 2])

The following changes are included in this series:
  [PATCH 1/2]: Introduce the "scoped" field to the ruleset structure in
               the user space interface, and add the restriction
               mechanism to Landlock.
  [PATCH 2/2]: Add three comprehensive tests for the new feature.

  Landlock: Add abstract unix socket connect restriction
  Landlock: Abstract unix socket restriction tests
