It was broken for several reasons:
* VOP_UNLOCK lost an argument in 13.0. So OpenZFS should be using
VOP_UNLOCK1, but a few direct calls to VOP_UNLOCK snuck in.
* The location of the zlib header moved in 13.0 and 12.1. We can drop
support for building on 12.0, which is EoL.
* knlist_init lost an argument in 13.0. OpenZFS change 9d0887402b
assumed 13.0 or later.
* FreeBSD 13.0 added copy_file_range, and OpenZFS change 67a1b03791
assumed 13.0 or later.
