debian/bin/gencontrol_signed.py: Make valid native version for signed source

dpkg-source strictly enforces that 3.0 (native) packages do not have
Debian revisions in their version strings, i.e. they cannot include
hyphens.

Replace the hyphen from the image binary version with a '+'.

Override this version back to what we want when building the signed
binary packages.
