Make X509V3_get_value_int free the old value before overwriting it.

This is an unexported API, so it's okay to change it. Many extension
types work by parsing a list of key:value pairs and then setting fields
based on it. If a key appears twice, it'll just overwrite the old value.

But X509V3_get_value_int forgot to free the old value when doing so.
