osdep/hurd: Support device entries with @/dev/disk: qualifier
Those are used with non-bootstrap disk drivers, for which libstore has to
open /dev/disk before calling device_open on it instead of on the device
master port. Normally in that case all /dev/ entries also have the @/dev/disk:
qualifier, so we can just drop it.
