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.
