    kboot: Add HOST_O_ constants for open, etc
    
    Add the common O_ constants for the open, fcntl, etc system calls. They
    are different than FreeBSD's. While they can differ based on
    architecture, they are constant for architectures we care about, and
    those architectures use the 'generic' version so future architectures
    will also work.
