56e8cb87c6 libprocstat: try to fix fallout from r361363
The revision caused libprocstat to have two undefined symbols:
- __start_set_pcpu
- __stop_set_pcpu
probably because of __GLOBL() used in sys/pcpu.h under _KERNEL.
The symbols are not accessed by anything and the linker in base does not
complain about them, but some ports are failing to build.
Hack around the problem by providing definitions for those symbols.

Probably there is a better solution, but I could not think of it yet.

8a719b0cee libprocstat: fix ZFS support
First of all, znode_phys_t hasn't been used for storing file attributes
for a long time now.  Modern ZFS versions use a System Attribute table
with a flexible layout.  But more importantly all the required
information is available in znode_t itself.

It's not easy to include zfs_znode.h in userland without breaking code
because the most interesting parts of the header are kernel-only. And
hardcoding field offsets is too fragile.  So, I created a new
compilation unit that includes zfs_znode.h using some mild kludges to
get it and its dependencies to compile in userland.  The compilation
unit exports interesting field offsets and does not have any other code.
