VP9 encoding progress broken on 1st pass

[nikolasr]

Summary of the bug:
When converting a video to VP9 (libvpx-vp9), the encoding progress is not displayed on first pass.
Instead of current frames and fps ffmpeg always outputs

frame=    0 fps=0.0 q=0.0 Lsize=N/A time=-577014:32:22.77 bitrate=N/A speed=N/A    /s speed=N/A

Things seem to go wrong beginning at commit 919638ff5c99e33d91974506b19d42dcee04690b.
Last known good is 4e145f1dcdcbe19e8f8e98940dab04e9332a8b5b, maybe even 4740fea7ddf5f81577c9f5a0c096a8a16a54716e (not sure about that).

At 919638ff5c99e33d91974506b19d42dcee04690b "time" display is still 0:0:0. To get the provided sample display try commit 2d924b3a630869c65fe0c76568910500f54ed057.

Expected "good" result should be a progress output of current frames and current fps.

Still present in git-master. Could any dev please take a look at it? Maybe Anton Khirnov, pretty please?

Seems to break libaom-av1, too (see #10165)

still unresolved :'-(
Bug is also present even in *stable* 6.0 release!
