kernel-devsrc: fix 32bit ARM devsrc builds
As a follow up to commit:
0fc66a0b64953 [kernel: provide module.lds
for out of tree builds in v5.10+], we must not only copy module.lds
from its new location, we have to not error when it isn't found in
the old location.
With this tweak, we have coverage on all supported arches for the
new location of module.lds, and backwards compatibility through
kernel versions.
