qcacld-3.0: Kbuild: Add support for nested composites

As a result of long path names and a large number of source files,
combined with upstream kernel build infrastructure changes, the
qcacld-3.0 build may encounter E2BIG errors when linking the final
wlan.o. To address this problem support for nested composite objects
is being added to the kernel. Update the Kbuild with the logic
required to take advantage of the nested composite support.
