Add 'ksft_exit_fail_msg()', if not run as root, with an appropriate
Warning.
Add 'ksft_print_header()' and 'ksft_set_plan()' to structure test
outputs more effectively.
Test logs:
Before Change:
- Without root
error: unshare, errno 1
- With root
No, output
After Change:
- Without root
TAP version 13
1..1
Bail out! Error : Need to run as root# Planned tests != run tests (1 != 0)
- With root
TAP version 13
1..1
