libpayload: arm: add code to clear bss

This adds some assembly code to clear .bss segment. It might have been
    already cleared by the loader, but it is not guaranteed. This also
    helps when the program is loaded by the debugger.

BUG=none
    TEST=observed that .bss is now initialized when the program is
         restarted. Verified correct boundaries of the segment.
