Fix build.
Update script for package-management related changes.

A hpkg will be created locally, which contains the firmwares. This hpkg will
be copied to system. IIRC, the firmware must live in their respective
subdirectories.

To note, once the approve_license flags are implemented on the end-user
applicacation side, the Intel ipw2100 and Intel ipw2200 could be moved
to a separate package. However (and IIRC) the Broadcom involves using a closed
binary blob, that should not become a pre-made package.
Fixed directories. Thanks jessica.

Note to self: Don't push on an empty coffee cup.
