[PATCH] Define the default version

[Jerry Van Baren <gerald.vanbaren@comcast.net>]

Jon, David:

Thanks for updating dtc to v17.  This is a trivial patch to fix the 
usage (permanently) to show the correct version number in the usage help.

Thanks,
gvb

The default version is used in two places (someday maybe more).  Create
a #define to set the default version in one place.
