sleep: fix printf format of fiemap fields

sleep: fix printf format of fiemap fields

Use PRIu64 and PRIu32 constants to also get the format right on LP-64
architectures.

For the 64-bit fields, we need a cast to (uint64_t), since __u64 is
defined as a `long long unsigned` and PRIu64 expects a `long unsigned`.
In practice, both are the same, so the cast should be OK.
