perl: Add lookup_network_has_flag() function.

This function can be used to check if a given address or network has one
of the following network flags.

* LOC_NETWORK_FLAG_ANONYMOUS_PROXY
* LOC_NETWORK_FLAG_SATELLITE_PROVIDER
* LOC_NETWORK_FLAG_ANYCAST

It will return true if the given flag is set.
