delete util/libreboot-utils (unused code)

this was an intense audit of nvmutil that somehow evolved
into writing a new, hardened implementation of mktemp.

it all works, a few memory bugs to solve on bsd, but i don't
see the point in keeping it. mktemp is fine, and nvmutil
already works.

lbutils implemented atomic writes and integrity checking,
in a manner completely overengineered for what it was
actually doing (modifying a few bytes in 8KB GbE files)

just delete it. i'll bring it back if i ever finish the
code. i don't want to leave dead/unfinished code in the tree.
