build: add default ignore network interface prefix

By default libnice now ignores network interfaces from virtual machines
and containers, i.e. names that start with "docker", "veth", "virbr" and
"vnet".

If you want to disable this feature override the default with

       ./configure --without-ignored-network-interface-prefix ...
       ./configure --with-ignored-network-interface-prefix= ...
       meson setup -D ignored-network-interface-prefix= ...
       meson setup -D ignored-network-interface-prefix=[] ...
