kpatch-build: Ubuntu signed/unsigned kernel image package fix

Browse Source 
In Ubuntu 18.04 LTS (but not in 16.04 LTS), the "linux" source package
no longer builds the "linux-image-*" binary kernel image packages
directly, but instead, it produces the "linux-image-unsigned-*" binary
packages, and the "linux-signed" source package then produces the
(signed) "linux-image-*" binary packages from the unsigned binaries.

This means that querying the target kernel's linux-image-* package for
its source package will yield a source package that is just a wrapper,
and does not actually contain the kernel source code.

Deal with this by removing the "-signed" substring from the kernel
source package name if it is present.  This makes kpatch-build work
on Ubuntu 18.04.
