build/boot/roms: use the new coding style

lbmk's new style is inspired by the bsd coding styles:
top-down logic, main simplified to a skeleton showing
overall program structure, variables well-defined,
rigorous (yet deceptively simple) error checking.

this was attempted before, but caused problems; coreboot
wasn't being cleaned properly, and rather than audit it,
i simply reverted this back to the old style.

this is actually attempt number 5, because i made 3 more
attempts between then and this one. i've build-tested this
using "./build boot roms all" (which is what b0rked on
the first attempt, months ago). it should be stable(tm).

the code is much nicer to read / work on now. this is the
beating heart of lbmk. get this script wrong, and you break
all of libreboot.
