delayacct: fix build regression on accounting tool

The accounting tool was modified for the original ABI using a custom
'timespec64' type in linux/taskstats.h, which I changed to use the regular
__kernel_timespec type, causing a build failure:

        getdelays.c:202:45: warning: 'struct timespec64' declared inside parameter list will not be visible outside of this definition or declaration

     202 | static const char *format_timespec64(struct timespec64 *ts)
         |                                             ^~~~~~~~~~

Change the tool to match the updated header.
