Special handling for the updater binary in the package creation script.

The updater binary is listed as a package on its own but is not
compressed.  The program downloading the update can then download
all packages for the new version including the updater executable
'package' (in reality, just the plain file) and then invoke that updater.

This also allows for substitution of the updater binary with a different
version via the -u parameter.
