kernel: provide module.lds for out of tree builds in v5.10+

The upstream commit 596b0474d3d [kbuild: preprocess module linker
script], adds a dependency on module.lds for external module
building.

Since module.lds is generated as part of 'modules_prepare', we
must make it available with the other kernel artifacts in the
kernel shared workdir, otherwise out of tree builds fail.

This fixes errors like:

    | make[4]: *** No rule to make target 'scripts/module.lds', needed by
        'build/tmp/work/qemuarm64-poky-linux/cryptodev-module/1.11-r0/git/cryptodev.ko'.
        Stop.
    | make[4]: *** Waiting for unfinished jobs....

We also ensure that kernel-devsrc has a copy to support on
target module builds that are often prepared with 'make scripts
prepare'. Those targets won't regenerate it, so the build fails.
If 'make modules_prepare' is used, the file will be regenerated
and overwrite our copy (as expected).
