In erl_interface there are three uses of `sprintf` to construct host
name strings. GCC 12 gives a `‘%s’ directive writing up to 254 bytes
into a region of size between 1 and 256` warning at these locations,
as it isn't smart enough to see that the manual bounds check is
correct and that the write is safe.

By switching to `snprintf` and removing the manual size calculation of
the resulting string, we can both simplify the relevant code and avoid
the warnings.
