Remove some non-determinism

Your app is not built reproducible in F-Droid, but we continuously test older versions on https://verification.f-droid.org/ and would like more and more apps to become repro.

Looking at the latest app report: https://verification.f-droid.org/packages/org.videolan.vlc/

Could you set the date in https://code.videolan.org/videolan/vlc-android/-/blob/3.6.5/application/vlc-android/build.gradle?ref_type=tags#L23 based on the last commit date instead? eg. git show --no-patch --format=%cd --date=format-local:'%Y-%m-%d'

Also, the machine name seems rather useless in https://code.videolan.org/videolan/vlc-android/-/blob/3.6.5/application/vlc-android/build.gradle?ref_type=tags#L24 imho

And the locale list should be sorted in https://code.videolan.org/videolan/vlc-android/-/blob/3.6.5/application/vlc-android/build.gradle?ref_type=tags#L128-L145
