fix _cupsGet1284Values

when 1284id doesn't end with semicolon，_cupsGet1284Values() cannot get last key and value.
eg.
uos@uos-PC:/usr/lib/cups/backend/snmp 10.10.120.220
network socket://10.10.120.220 "Unknown" "FUJI XEROX ApeosPort-V 4070 v  3. 43.  0 Multifunction System" "MANUFACTURER:FUJI XEROX;MODEL:ApeosPort-V 4070" ""
