abuild: change board identifier to a variant of CONFIG_BOARD_*

Since we now have multiple boards in a single mainboard directory (eg
    google/veyron), we need some other identifier from which to create
    output directories and filenames in abuild than the directory name.
    Use the wildcard part of CONFIG_BOARD_* instead.

This changes the semantics of payload.sh handling: it's passed the
    single new identifier instead of two arguments "vendor" and "board" that
    constitute the mainboard directory's path.
