run: include sys/stat.h again

This partially reverts 9adb4685dffadb3991535a8d990ce35132b6d9a6.

For the case that sys/stat.h is not included indirectly by other headers.
Fixes the following error:
```
../src/run/run.c: In function 'fchown_to_capsule':
../src/run/run.c:2128:21: error: storage size of 'st' isn't known
 2128 |         struct stat st;
      |                     ^~
```
