Add copyright acknowledgements to distributed files
This doesn't detect the dual FTL _OR_ GPL2+ licencing of freetype since its per file HEADERs only refer to "the FreeType project license, LICENSE.TXT", which details the dual licensing. However, this should be fine since we can just decide to use FTL. Some path exclude rules were added for files not actually included in the binaries, but having additional licenses or borking licensecheck's copyright detection.
