wrong scripting in /usr/bin/emby-theater

[mk01]

guys,

wrapper to emby-theater (/usr/bin/emby-theater) is wrongly handling the params from /etc/emby-theater.conf.

    if [ ! $EMBY_SYSTEM_LIBVA_DRIVERS ]; then
        export LIBVA_DRIVERS_PATH=$APP_DIR/extra/lib/dri
    fi

[ ! xxx ] is evaluated as [ ! -n xxx ], that means that export will never be effective as long as the variable is existing and not empty. so use either

    if ! $EMBY_SYSTEM_LIBVA_DRIVERS; then

or

    if [ x$EMBY_SYSTEM_LIBVA_DRIVERS = xfalse ]; then

maybe not so visible in latest version (as the variable is true), but ver 3.0.19 had EMBY_SYSTEM_LIBVA_DRIVERS set to false, so regardless the system libs were used.
