Subject: [PATCH] Update packaging bits to build scst-dbg package

This commits updates the Debian packaging bits to build scst-dbg
package for kernel modules linked with debug kernel.

SCST kernel modules linked with debug kernel need to packaged
differently so that they can co-exist with SCST package for
modules built for production kernel.

The updates in packaging bits are minimal would only apply if
KVERS environment variable is configured for debug kernel for
TrueNAS SCALE.
