PATCH v4 1/1 Testing statx syscall Timestamp fields

The time before and after the execution of the corresponding system call is noted.

It is checked whether the time returned by statx lies in this range.

open syscall with O_CREAT flag for birth time.
write syscall for modified time.
read syscall for access time.
chmod syscall for status change time.

PATCH v4 1/1 Testing statx syscall Timestamp fields

Hi!
Pushed with minor changes, thanks.

* Changed the tst_test structure to pass -I 256 instead of specifying minimal size for the image

* Removed additional \n from the TPASS message
