[Fuchsia] Add DnsConfigServiceFuchsia stub
Previously DnsConfigServicePosix was compiled on Fuchsia, but none of
that code works there. Added a stub implementation of
DnsConfigService for Fuchsia that returns an emtpy config. This change
unblocks work on DnsConfigServicePosix unittests. DNS resolver falls
back to the system provided resolver when it gets an empty DNS config.
