programs/fuzz: set sensible default CFLAGS
Running make from programs/fuzz didn't set any optimization flags (running
make from programs or from the root inherited the parent's optimization
flags). Default to -O2.
There were no -W flags. Default to -Wall -Wextra, but not -Werror in line
with the other makefiles.
