fftools/ffmpeg_mux_init: apply encoder options manually

Do not pass an options dictionary to the avcodec_open2() in enc_open().

This is cleaner and more robust, as previously various bits of code
would try to interpret the contents of the options dictionary, with
varying degrees of correctness. Now they can just access the encoder
AVCodecContext directly.

Cf. 372c78dd42 - analogous change for
decoding.

A non-progressive field order is now written on the container level in
interlaced ProRes encoding tests.
