Subject: [PATCH] kbuild: deb-pkg: Include modules.builtin* even if non-modular

Even for a non-modular kernel, the kernel builds modules.builtin and
modules.builtin.modinfo, with information about the built-in modules.
Tools such as initramfs-tools need these files to build a working
initramfs on some systems, such as those requiring firmware.

Install modules.builtin and modules.builtin.modinfo into the linux-image
package even for a non-modular kernel.
