xargs: implement -P0

This simple patch implements GNU-like xargs -P0 to run "as many processes as
possible". This option is convenient and allows many of my scripts to port.

There are a couple of differences from GNU behavior to make this consistent
with other options in our xargs: -P takes negative numbers, which mean the same
as -P0, and the maximum number of procs is equal to maxargs rather than some
*_MAX macro. This is probably what the user wants, performs a lot better, and
doesn't hurt intended -P0 portability.

Tested with: kyua test -k /usr/tests/Kyuafile usr.bin/xargs (passed)
