[PATCH 5.9 544/757] kbuild: deb-pkg: do not build linux-headers package if CONFIG_MODULES=n

From: Masahiro Yamada <masahiroy@kernel.org>

[ Upstream commit bac977cbc0d6731fb8e67c2be0e4acbd959e10b3 ]

Since commit 269a535ca931 ("modpost: generate vmlinux.symvers and
reuse it for the second modpost"), with CONFIG_MODULES disabled,
"make deb-pkg" (or "make bindeb-pkg") fails with:

find: ‘Module.symvers’: No such file or directory

If CONFIG_MODULES is disabled, it doesn't really make sense to build
the linux-headers package.

Fixes: 269a535ca931 ("modpost: generate vmlinux.symvers and reuse it for the second modpost")
