[JGIT PATCH 02/10] Make ObjectEntry's position field private

["Shawn O. Pearce" <spearce@spearce.org>]

PackWriter calls this getOffset() and hides the field as a private
field as part of its related ObjectToPack class.  We do that here
as part of ObjectEntry's API so we can later replace that part of
ObjectToPack by inheriting from ObjectEntry.
