MDEV-26136: Correct AIX/macOS cast warning (my_time.h)

Browse source 
tv_usec is a (suseconds_t) so we cast to it. Prevents the AIX(gcc-10) warning:

include/my_time.h: In function 'void my_timeval_trunc(timeval*, uint)':
include/my_time.h:249:65: warning: conversion from 'long int' to 'suseconds_t' {aka 'int'} may change value [-Wconversion]
  249 |   tv->tv_usec-= my_time_fraction_remainder(tv->tv_usec, decimals);
      |

macOS is: conversion from 'long int' to '__darwin_suseconds_t' {aka 'int'} may change value

On Windows suseconds_t isn't defined so we use the existing
long return type of my_time_fraction_remainder.
