[Buildroot] [PATCH 1/1] janus-gateway: add option for libcurl support

[Olivier Maignial]

libcurl is not mandatory to compile Janus, but Janus use it in several way:
    - RTSP stream support in plugin streaming
    - TURN REST API support
    - HTTP backend for text room plugin
    - ...
This commit add an option "libcurl support" to add dependency on libcurl.
