st/va: add enviromental variable to disable interlace

Browse source 
Add environmental variable to disable interlace mode. At VAAPI decoding stage, driver can not distinguish b/w pure decoding case and transcoding case. And since interlace encoding is not supported, we have to disable interlace for transcoding case. The temporary solution is to use enviromental variable to disable interlace mode.
