sysctl: enable pattern matching with path

Pattern matching support in `sysctl: implement --pattern option'
commit did not work when variable path was defined, for example

$ sysctl net.ipv4 -r arp.ignore

gave no output. Reason being was tht the pattern was matched agains
the specified argument and not the output variable list.
