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
