Drop lbtdump, like it's 2007
We have discussed dropping lbtdump since 2007, since it was obsoleted
by lxbios (nowadays aka nvramtool) back then.
http://www.coreboot.org/pipermail/coreboot/2007-August/024188.html
Well, it's only eight years later.

-lbtdump is a utility to dump the coreboot table
-to a human readable form.
-
-This needs to be run as root (or setuid) on a system
