Support kernel modules in vendor, recovery images

Support BOARD_VENDOR_KERNEL_MODULES which accepts a list of the
kernel module binaries. Binaries listed there are copied to
$(TARGET_OUT_VENDOR)/lib/modules and 'depmod' is executed to generate
the dependencies. BOARD_RECOVERY_KERNEL_MODULES is similarly
implemented to provide a way to specify kernel modules to be copied
to the recovery image.
