rust/timer: Define NANOSECONDS_PER_SECOND binding as u64

Browse source 
NANOSECONDS_PER_SECOND is often used in operations with get_ns(), which
currently returns a u64.

Therefore, define a new NANOSECONDS_PER_SECOND binding is with u64 type
to eliminate unnecessary type conversions (from u32 to u64).
