catch and rescue from looking up non-existent facts when looking for 'kind'

facter (2.x) only provides facts without interface suffix for
 * ipaddress
 * netmask

'macaddress' and 'network' facts will always have the related interface
name appended. in turns lookupvar throws errors when strict_variables is
enabled.
