Read vendor_boot.modules.load and vendor_dlkm.modules.load

Browse source 
Previously, we copied all available kernel modules into the vendor_boot
ramdisk except for approx. 14 modules that we explicitly excluded.

Going forward, the kernel build will distribute the two additional files
vendor_boot.modules.load and vendor_dlkm.modules.load which define,
respectively, the lists of modules that should be loaded from
vendor_boot and vendor_dlkm.

The contents of the two *.modules.load files will be copied almost
verbatim into modules.load files in the respective images except for the
fact that the directory names of the .ko files are stripped. So, for
example, kernel/net/core/pktgen.ko becomes just pktgen.ko.

Additionally, we only copy those .ko files into the vendor_boot image
that are listed in vendor_boot.modules.load. On the other hand, the
vendor_dlkm partition image will contain all .ko files regardless of
whether they are listed in vendor_dlkm.modules.load.
