Update the list of installed packages for building ONIE

The debian-prepare-build-host Makefile target can be used to download
and install the necessary development packges for apt-get based Linux
distributions.

This patches adds additional packages to the
DEBIAN_BUILD_HOST_PACKAGES variable in the main Makefile.

Testing Done:

Built ONIE using a new Ubuntu 14.04 system.  Previously, without this
patch the build would fail for missing development host packages.
