Subject: [PATCH] Coin: Dynamically linked FFmpeg for Android (on Windows host)

Prepare install-ffmpeg.ps1 script for turning on dynamically
linked FFmpeg on Windows.

Script on Windows will use MSYS2 and run same bash script as Linux host.
To make it possible first need to install binutils (for readelf) and
patchelf. As patchelf is not available by pacman, it is compiled and
installed from sources.

Task-number: QTBUG-122010
