dragonboards: Enable system_dlkm partition support

Enabling system_dlkm partition support. We plan to use it to
flash and use system_dlkm.img prebuilt from ci.android.com
directly. For now this partition is just a stub or place
holder while we segregate vendor kernel modules into
vendor_ramdisk and vendor_dlkm groups.

We are re-using dlkm_vendor service, hosted by Cuttelfish
project, which will take care of modprobing kernel modules.
