Update Makefile

This patchset updates the Makefile to process all subfolders except an
explicitly specified EXCLUDES-list.  This would avoid developers adding
new charts from needing to modify the Makefile, except for needing it
be excluded.  Also, this would eases the process of later migrating and
integrating charts across OSH, OSH-infra, OSH-addons, etc.
