- Add skip test 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

- With root TAP version 13 1..1
