Disabling h264 and hevc decoders needs disabling av1_vulkan hwaccel as well

[bbhtt]

Summary of the bug:

For patent reasons, h264 and hevc is usually disabled for free builds. But
with 6.1 that seems to need disabling the av1_vulkan hwaccel capability too. This seems like a bug because av1 decoder is not being disabled.

How to reproduce:

With 6.1 tarball

./configure --disable-decoder="h264,hevc" --disable-static --enable-shared --disable-hwaccel="h264_vulkan,hevc_vulkan"

What works is disabling av1_vulkan as well, i.e. completely, since those 3 are only supported for now.

Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.

Looks like this was already fixed with ​https://github.com/FFmpeg/FFmpeg/commit/8c117b75afa3c6b824fab85ec6716dbe3ba975be
