vlc: fix freerdp module build

Since we are building "freerdp" again, build can now fail
due to reliance on removed APIs. For instance :
http://errors.yoctoproject.org/Errors/Details/20603/

Fix this by conditionally building the module, and if we
build it, patching the code until the fix gets merged
upstream.
