rust: task: Add Rust version of might_sleep()
Add a helper function equivalent to the C's might_sleep(), which
serves as a debugging aid and a potential scheduling point.
Note that this function can only be used in a nonatomic context.
This will be used by Rust version of read_poll_timeout().
[boqun: Use file_from_location() to get a C string instead of changing
__might_sleep()]
