Fix module_path/line numbers in log facade logging

Previously, we'd reuse the `log` facade macros which would always log
the line number in `logger.rs`, not at the line number given at the
record.

Here, we rectify this by utilizing `log`'s `RecordBuilder` to craft a
record and directly giving it to the configured logger.
