Revert "pidfd: prevent creation of pidfds for kthreads"

This reverts commit 3b5bbe798b2451820e74243b738268f51901e7d0.

Eric reported that systemd-shutdown gets broken by blocking the creating
of pidfds for kthreads as older versions seems to rely on being able to
create a pidfd for any process in /proc.
