[Buildroot] [PATCH 3/3] packages: ensure linux supports modules even when not using kernel-module

[Yann E. MORIN]

Some packages build kernel modules without using the kernel-module infra
(because they use custom build systems); they do not automatically get
the kernel to support modules which is ensured when using the infra.

It must be done manually for all those packages.
