This patch adds an optional parameter to the provisioning script
'install-ffmpeg-macos.sh', allowing us to override the output directory
for which the finalized library is installed.
This is particularly useful for local builds, where we often need
multiple different versions of FFmpeg installed, for different Qt
versions.
This patch has no impact for existing coin workflows.
