[PATCH] linux-distro: Fix multiple provider warnings

[Jan Kiszka <jan.kiszka@siemens.com>]

From: Jan Kiszka <jan.kiszka@siemens.com>

As now all recipe variants of this stub target provide the same, we get
warnings like these when using the distro kernel:

NOTE: Multiple providers are available for linux-image-arm64 (linux-distro, linux-distro-native)
Consider defining a PREFERRED_PROVIDER entry to match linux-image-arm64

We can resolve that by limiting the PROVIDES additions to the base
target again as all of them are stubs anyway, Debian will provide the
actual packages.

Fixes: b7e3c78766c3 ("module.inc: fix kbuild dependency")
