>Description:
cmake built on NetBSD/sparc picks up wrong ps(1) invocation.

Trying to run cmake on self (the language) I get:

...
-- Preparing for NetBSD on sparc
ps: unknown option -- f
usage:  ps [-AaCcdehjlmrSsTuvwx] [-G group] [-k key] [-M core] [-N system]
           [-O fmt] [-o fmt] [-p pid] [-t tty] [-U user] [-W swap]
        ps -L

The problem is in Source/kwsys/ProcessUNIX.c:2485 where
KWSYSPE_PS_COMMAND macro is defined.

There is no case that handles NetBSD, so a case further down the #if
tree is picked up (b/c of __sparc).

>How-To-Repeat:
Build cmake on sparc.  I don't know anything about cmake.
Get a copy of https://github.com/nbuwe/self/tree/feature/netbsd-macppc
and do e.g.

  $ cmake -B build -DCMAKE_BUILD_TYPE=Debug .

>Fix:
Explicitly handle NetBSD in that #if
