Add BSM conversion logic for some jail and setlogin class events

[csjp]

Summary

Currently kernel audit events for jail_set(2), jail_get(2), jail_attach(2),
jail_remove(2) and finally setloginclass(2) are not being converted and
committed into userspace. Add the cases for these syscalls and make sure
they are being converted properly.

Test Plan

After the change I see records being converted and committed to userspace:

header,102,11,jail_set(2),0,Fri Feb 28 18:24:42 2020, + 482 msec
path,/
attribute,755,root,0,90,2,5064
subject,root,root,0,root,0,886,0,0,0.0.0.0
return,success,1
trailer,102

Not my expertise of code but looks ok to me.

Break out the switch case statements for the new syscalls
