Subject: [PATCH v5 1/2] selftests: tmpfs: Add Test-fail if not run as root

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
