removal of skeletal PUP-1 support

[Steven M. Schultz]

	Not quite sure why the 'netpup' stuff was carried along all this
	time, the skeletal support for PUP-1 has been long gone from
	sys/uipc_domain.c.  

	Here are the diffs to complete the removal of the PUP-1 remnants,
	saves a few disc sectors and a few seconds when making a kernel.

	After applying these diffs to /sys/conf/{Make.net,Make.nsunix,config}
	do a "rm -r /sys/netpup" to complete the job.  You'll probably
	also want to remove "npup.h" and edit the Makefiles for kernels
	already config'd.
