Fix recording duration flag

[hunterjm]

Breaking change

pyAV >7.0.0 drops support for FFmpeg versions <4.0. FFmpeg will need to be updated to at least 4.0 for stream to work. If you run supervised or docker, no manual intervention is needed. Alternative installs can check the stream integration documentation for troubleshooting tips.

Proposed change

Bump the pyAV lib to 7.0.1 which exposes new flags that can be used to fix the recording duration as stored in the file header. This was tested locally and fixed the issue layed out in #34605. The existing tests that are marked as skipped were included when running pytest locally and all passed.

@pvizeli - It looks like we may need to update the version of FFMPEG on our CI images. The official Home Assistant docker images using Alpine should meet the FFMPEG requirement for this library without issue.

This doesn't need to go out in 0.109 since beta is already cut. It's a low impact bugfix.

Untagged this from the milestone. It only fixes a rare case issue. Probably better wait until next release? (unless you've already updated all images Pascal, in that case proceed)

[pvizeli]

@balloob we support ffmpeg4 a long time. Just the CI not. I updated it, so the CI should work now. But I'm fine with that

Not sure what to do with code coverage here. Tests are written that cover this code, and they work as intended when enabled locally. They were disabled back when we were on CircleCI because they were deemed flaky.

Edit: If we want to keep them disabled, I can add them to .coveragerc
