lbmk: remove use of deprecated ./vendor command

use ./mk instead, because in a future change to lbmk,
only ./mk will be used and the other commands will
be removed.

with this change, the ./vendor, ./build and ./update
commands are no longer used. these commands still work,
for backwards compatibility, but they are deprecated.
