add BOARD_*_KERNEL_MODULE_ARCHIVE support

It may be the case that the list of kernel modules to be copied into
various partitions is not known at the time the build is invoked. To
support this configuration, create a set of make variables, each of
which can be set to the path of a zip archive of kernel modules to be
used.

      kernel modules into zip, build and verify *.ko in vendor
