fftools/ffmpeg_filter: fix NULL pointer dereference
In close_output(), a dummy frame is created with format NONE passed
to enc_open(), which isn't prepared for it. The NULL pointer
dereference happened at
av_pix_fmt_desc_get(enc_ctx->pix_fmt)->comp[0].depth.
When fgt.graph is NULL, skip fg_output_frame() since there is
nothing to output.
