UBUNTU: Add version specific firmware delivery mechanism

BugLink: http://bugs.launchpad.net/bugs/1170739

The udev rules for finding firmware are already uniquely
tied to an ABI number. Now we provide a way to deliver firmware
that is consumed by the compat wireless drivers.

UBUNTU: Add Conflicts: for compat-wireless stacks

BugLink: http://bugs.launchpad.net/bugs/1068751

We allow multiple upstream versions of the compat-wireless stack to be
packaged and installed via LBM. There currently exists a potential for
conflicts when installing multiple versions. Add a Conflicts: statement
to the control file to ensure only a single stack can be installed at a
given time.
