Use TH_LOG to report failure when reading /proc/<pid>/stat in
get_proc_stat(), following kernel test framework conventions.

Previously, printf() was used which is discouraged.

v1 -> v2:
- Used TH_LOG instead of printf for error logging
- Moved variable declaration to the top of the function
- Applied review suggestion by Kees Cook
