Replace direct error handling with 'ksft_test_result_*',
'ksft_exit_fail_msg' macros for better reporting.


Don't fail the test - skip is the right exit code in this case.

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)

This should be a skip -- see above.

Totals: pass:0 fail:0 xfail:0 xpass:0 skip:0 error:0

- With root
TAP version 13
1..1
ok 1 Test : Success
Totals: pass:1 fail:0 xfail:0 xpass:0 skip:0 error:0

This looks right.
