abuild: make build directory configurable with a variable

Allow overriding the build directly (default: coreboot-builds)
    using the COREBOOT_BUILD_DIR variable, in addition to setting
    it through the -o parameter.
    This helps with build nodes where jenkins wants to run the
    same command everywhere but allows different environment
    variables.
