fftools/ffmpeg_dec: abort if avcodec_send_packet() returns EAGAIN
As the comment in the code mentions, EAGAIN is not an expected value here because we call avcodec_receive_frame() until all frames have been returned. avcodec_send_packet() returning EAGAIN means a packet is still buffered, which hints that the underlying decoder is buggy and not fetching packets as it should. An example of this behavior was in the libdav1d wrapper before f209614290, where feeding it split frames (or individual OBUs) would result in the CLI eventually printing the confusing "Error submitting packet to decoder: Resource temporarily unavailable" error message, and just keep going until EOF without returning new frames.
