We use git_config_get_string() to retrieve the expiry value in a newly
allocated string. But after parsing it, we never free it, leaking the
memory.
We could fix this with a free() obviously, but there's an even better
solution: we can use the non-allocating "tmp" variant of the function;
we only need it to be valid for the lifetime of our parse function.
