[build system] cleanup --enable-snmp by removing ucd-snmp cruft

2006-01-31 Paul Jakma <paul.jakma@sun.com>

	* configure.ac: Cleanup the hideous {net,ucd}-snmp section
	  by removing ucd-snmp. Hence fixing detection where
	  net-snmp is installed in /usr/local (Boris Kovalenko reported
	  the problem).
