Subject: [PATCH v4 1/7] rust: time: Add PartialEq/Eq/PartialOrd/Ord trait to Ktime

Add PartialEq/Eq/PartialOrd/Ord trait to Ktime so two Ktime instances
can be compared to determine whether a timeout is met or not.

Use the derive implements; we directly touch C's ktime_t rather than
using the C's accessors because more efficient and we already do in
the existing code (Ktime::sub).
