Revert "jail: Optionally allow audit session state to be configured in a jail"

Changing audit system calls to return EPERM instead of ENOSYS when
invoked from a jail breaks some userspace applications. Revert for now
until a more complete change is reviewed.

This reverts commit 246d7e9fc23928be22db38220f5439f5cdee5264.
