stun: Use sprintf() instead of snprintf() to support VS 2010

Visual Studio 2010 still doesn’t support C99, and snprintf() is a C99
function, so compilation fails with:
    error: C3861: 'snprintf': identifier not found

Use sprintf() instead, which is C89 and thus supported. This does not
make the code unsafe, as the format specifier is constrained to two
characters (+ trailing nul), which are guaranteed to fit in the array
bounds.
