lib.sh: remove badcmd()

it's bloat. telling the user to rtfm is something that
we already do on irc; they will still ask how to do
everything, and ignore the message from badcmd(), or
they will automatically know to rtfm.

i'm on a massive purge, removing bloat from lbmk as
part of Libreboot Build System Audit 6.

all bloat must go.
