trace: forbid floating point types
Only one existing trace event uses a floating point type. Unfortunately float and double cannot be supported since SystemTap does not have floating point types. Remove float and double from the whitelist and document this limitation. Update the migrate_transferred trace event to use uint64_t instead of double.
