Default UBUNTU: Add symlinks to broadcom firmware files

The brcm80211 module tries to load non-existent firmware and thus throws
the following type of error:

brcm80211: fail to load firmware brcm/bcm43xx-0.fw
brcm80211: Failed to find firmware usually in /lib/firmware/brcm

The necessary firmware is actually available at:

/lib/firmware/brcm/bcm43xx-0-610-809-0.fw
/lib/firmware/brcm/bcm43xx_hdr-0-610-809-0.fw

Adding symlinks to the proper files resolves the issue and has been
confirmed by the bug reporter to allow the driver/device to operate as
expected.

Pull request is as follows, please consider applying to the Natty
linux-firmware package.

While symlinks will solve this particular problem, its not the way the
rest of the firmware files are used. I think we should simply rename the
firmware file to what the driver is expecting. That way its clear on the
next update that you have to rename your incoming versioned file to
something the driver can load (bcm43xx-0.fw for example). Its also
consistent with the way the rest of the firmware files are handled. We
also keep track of the firmware version number in WHENCE.

Sounds reasonable to me. The updated pull request below renames the
files rather than creating symlinks.
