CBFS: Change how the bss is zeroed when loading a stage.

For reasons explained in a previous CL, it might be necessary to "load" a file
    from CBFS in place. The loading code in CBFS was, however, zeroing the area of
    memory the stage was about to be loaded into. When the CBFS data is located
    elsewhere this works fine, but when it isn't you end up clobbering the data
    you're trying to load. Also, there's no reason to zero memory we're about to
    load something into or have just loaded something into. This change makes it
    so that we only zero out the portion of the memory between what was
    loaded/decompressed and the final size of the stage in memory.
