The actual resolver is in the [log_file_open](https://github.com/agroal/pgagroal/blob/babd4c76be1521447713041a62c591f91b271986/src/libpgagroal/logging.c#L243), thus make the env works in `log_path` only. **Expected solution:** - Integrates `pgagroal_resolve_path` into [extract_syskey_value](https://github.com/agroal/pgagroal/blob/babd4c76be1521447713041a62c591f91b271986/src/libpgagroal/configuration.c#L283) so the function returns error if the value isn't good path.
