Fix #104263: Error performing BAT pack in Windows with shared storage

Replace calls to `Path.absolute()` and `Path.resolve()` with
`bpathlib.make_absolute(path)`.

The replaced functions can transform drive letters on Windows to UNC
notation. Either all of Flamenco + BAT should be using UNC notation, or
drive letters, but mixing those will cause errors.
