package/libwebsockets: (re-)enable external poll loop support

Browse Source 
Since version 3.2.0, libwebsockets does not compile its external loop
support code anymore. That code was put under LWS_WITH_EXTERNAL_POLL
compile option, which defaults to OFF.

Applications relying on that support need to turn that option on, so
let's add it to the package.

For example, when libwebsockets is enabled, mosquitto broker is built
with websocket support, but its code requires LWS_WITH_EXTERNAL_POLL
to be on, otherwise it gives compile-time warning hinting to unusable
websocket support:
