kbuild: deb-pkg: Don't fail if modules.order is missing
[ Upstream commit bcbbf493f2fa6fa1f0832f6b5b4c80a65de242d6 ]
Kernels built without CONFIG_MODULES might still want to create -dbg deb
packages but install_linux_image_dbg() assumes modules.order always
exists. This obviously isn't true if no modules were built, so we should
skip reading modules.order in that case.
Fixes: 16c36f8864e3 ("kbuild: deb-pkg: use build ID instead of debug link for dbg package")
