Re: [PATCH v2 15/27] selftests/landlock: Close leaked file descriptors

Several tests do not close file descriptors they open: the /dev/null FD
in restrict_self_fd and restrict_self_fd_flags, and the parent's ends
of the synchronization pipes in various ptrace, audit, signal and
abstract UNIX socket tests.

Close them once they are not needed anymore.
