Subject: [PATCH] Record build customizations in BuildDetails.plist

Customizations declare themselves with an empty <identifier>.loopcustomization file at the workspace root or a submodule root. The build-details script collects the identifiers into com-loopkit-Loop-customizations, and the diagnostic report lists them.
