mprintf: use snprintf if available
This is the single place in libcurl code where it uses the "native"
s(n)printf() function. Used for writing floats. The use has been
reviewed and vetted and uses a HUGE target buffer, but switching to
snprintf() still makes this safer and removes build-time warnings.
