[PATCH] make it possible for yp_mkdb to send YPPROC_CLEAR to arbitrary host

I have a patch that makes it possible to send an YPPROC_CLEAR to any 
host, not just localhost.  YPPROC_CLEAR is basically used to flush NIS 
connections, so that clients pick up changes done in the NIS maps right 
away.  Currently yp_mkdb can send this to localhost, but if the 
NIS-server is in a jail, there is no localhost.  This way YPPROC_CLEAR 
can be sent to the NIS server in jails as well.
The patch is attached and also in bin/169911 [1]
