Redox: Return true from Path::is_absolute if a Path contains root or a scheme

In Redox, different subsystems have different filesystem paths. However, the majority of applications using the `Path::is_absolute` function really only want to know if a path is absolute from the perspective of the scheme it is currently running in, usually `file:`. This makes both `file:/` and `/` return `true` from `Path::is_absolute`, meaning that most code does not have to check if it is running on Redox.

Code that wants to know if a path contains a scheme can implement such a check on its own.
