libpayload: Add -Os to the CFLAGS
Adding -Os to the CFLAGS gains us about 25% smaller code (give or take).
Unfortunately, it exposes a strange issue where strcpy() suddenly goes
missing - we think that strcpy() is being provided by libgcc, and that
for some reason, -Os changes the beahavior. Oh, well - add a quick
strcpy() function and we're good.
