CMake: Silence CMP0048 warnings

Browse source 
When libwebsockets is included as a subdirectory in other projects that rely on a minimum CMake version of 3.x, a CMP0048 policy warning will be raised due to the project not specifying a version in the project call.

This patch silences the warning by explicitly setting the policy within libwebsockets to NEW if it has already been forwarded as such, without any further impact on the behavior of CMake.
