The fallback function (gf_vsnprintf) to provide a vsnprintf function
if the system library doesn't have one would not compile due to the
variable name for the string's destination buffer not being updated
after the refactor in 2018 in edaaef601d.
This updates the internal logic of gf_vsnprintf to now use the str
variable defined in the function signature.
