Remove netlink-client dependency from net-module-wifi.

Attempted to import net-utils-device-common lib in netlink-client
to use Structure stuff and RdnssOption class to parse RDNSS RA
option from the netlink message. However, seems to be some dependency
issue like:

Dependency path:
    via tag apex.dependencyTag: { name:javaLib payload:true sourceOnly:false}
-> service-wifi{os:android,arch:common,apex:apex10000}
       via tag java.dependencyTag: { name:staticlib}
-> wifi-service-pre-jarjar{os:android,arch:common,apex:apex10000}
       via tag java.dependencyTag: { name:staticlib}
-> services.net-module-wifi{os:android,arch:common,apex:apex10000}
       via tag java.dependencyTag: { name:staticlib}
-> netlink-client{os:android,arch:common,apex:apex10000}
       via tag java.dependencyTag: { name:staticlib}
-> net-utils-device-common{os:android,arch:common,apex:apex10000}
       via tag java.dependencyTag: { name:staticlib}
-> net-utils-framework-common{os:android,arch:common,apex:apex10000}

If the net-module-wifi doesn't require netlink-client lib, then
probably we can remove the netlink-client dependency and fix above
conflict.
