Commit Message

This commit adds test to check if getrusage works correctly. As the
first check - if the wrong 'who' parameter causes errno set to EINVAL.

Next for the ru_{us}time.tv_usec fields it is checked if they are in
microseconds range.

The last check is to perform busy wait loop for 10ms and afterwards
assess if ru_{us}time.tv_sec are not smaller than values read on the
test start.

Changes for v2:
- Add check for EINVAL return value
- Check if getrusage ru_{su}time.tv_usec are in correct microseconds range
- Busy wait for 10ms and then compare getrusage system and user times
  (in seconds) if they are equal or larger than previous ones
