image_types_ostree: allow to add layer specific OSTree commit arguments

The OSTree commit command allows to add metadata to the commit. This
might be customized in a distro layer for distribution specific needs.
Allow to pass extra arguments using EXTRA_OSTREE_COMMIT variable
(using a variable named similar to EXTRA_OEMAKE used to pass extra make
arguments).
