utime.h: fix OVERFLOW_BEFORE_WIDEN

CID 1274295 (#1 of 1): Unintentional integer overflow (OVERFLOW_BEFORE_WIDEN)
 overflow_before_widen: Potentially overflowing expression
 usec * 1000 with type int (32 bits, signed) is evaluated using
 32-bit arithmetic before being used in a context which expects
 an expression of type uint64_t (64 bits, unsigned).
