Joachim Wiberg 5a3972714a keventd: defer pidfile until coldplug queue is drained ...

When started with -c (the default when keventd is the device manager),
gate the pidfile on the kernel's uevent_seqnum having been stable for
200ms.  Up to now ready signaling with the pidfile was done right after
coldplug() triggered the kernel to re-emit events, but before uev_run()
had drained any of them, so <pid/keventd> really only meant "listening
on netlink".

With the gate, services that depend on <pid/keventd> can now assume /dev
is populated and persistent symlinks are live.
