kbuild: builddeb: always make modules_install, to install modules.builtin*

[ Upstream commit 4243afdb ]

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.

Now that `make modules_install` works even in non-modular kernels and
installs these files, unconditionally invoke it when building a Debian
package.
