Remove get_myaddress

Just use INADDR_LOOPBACK for pmap_dump.
glibc already uses the loopback interface for pmap_set, pmap_unset.

-# Warning: don't do this unless you are really desperate!!
-#
-# Makefile to build a shared object that forces RPC servers to register
-# and unregister with the portmapper through the loopback interface
-# instead of via the primary network interface address.
-#
-# This is a desperate attempt to prevent an attacker from using source
-# address spoofing to manipulate your portmapper tables. For this to be
-# effective you need to build the portmapper with -DLOOPBACK_SETUNSET,
-# and you need to disable IP source routing in the UNIX kernel.
-#
-# Quick summary of what to do to trick your rpc servers into cooperation:
-#
-# 1 - In the text below, uncomment the SH_CC and SH_LD definitions that are
-# appropriate for your environment. Then type:
-#
-#      make -f Makefile.shcc
-#
-# 2 - Install the get_myaddress.so shared object in a suitable place, for
-# example in the /usr/local/lib directory.
-#
-# 3 - Edit your system startup files so that the rpc servers use the
-# get_myaddress.so shared object. For several environments, the text below
-# gives an example in bourne-shell syntax of how how to start an rpc server.
