av1 encoder crash fixed by enabling runtime cpu detect

[juha-h]

I got same kind of crash as I reported here #111 but now with av1 encoder. The crash got fixed by this patch:

Same issue was found and fixed the same way here https://github.com/obsproject/obs-deps/pull/238/files.

Its is OK for me to patch ffmpeg-android-maker, but it would be nice if it would possible to have ffmpeg-android-maker parameters or a config file instead.
