[PATCH] delayacct: fix build regression on accounting tool

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

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.

Closes: https://lore.kernel.org/r/202602091611.lxgINqXp-lkp@xxxxxxxxx/
Fixes: 503efe850c74 ("delayacct: add timestamp of delay max")
Fixes: f06e31eef4c1 ("delayacct: fix uapi timespec64 definition")
