Give jail descriptors the same kevent flags as jails. Also fix the
event reporting in jails, where it was including data for events the
user didn't ask for.

Instead of using the EVFILT_PROC model of attempting to automatically
register new events when a child jail is created, just give a single
event when a child jail is created. As was already done with jail
attach events, make a best-effort report of the added jail's id in
kn_data. If the are multiple NOTE_JAIL_CHILD and/or NOTE_JAIL_ATTACH
events, set the NOTE_JAIL_MULTI flag, and don't report anything in
data, indicating that the caller will need to query the system state
on their own.

Add kqueue tracking to jails, inspired by how it's done with processes.
EVFILT_JAIL takes a jail ID, and tracks with NOTE_JAIL_SET,
NOTE_JAIL_ATTACH, NOTE_JAIL_REMOVE, and NOTE_JAIL_CHILD. It also uses
the NOTE_TRACK mechanism that EVFILT_PROC uses, using the same result
flags (NOTE_CHILD and NOTE_TRACKERR).
