Replace direct error handling with 'ksft_test_result_*' macros for better reporting.
Test logs:
Before change: - Without root error: unshare, errno 1
- With root No, output
After change: - Without root TAP version 13 1..1 ok 2 # SKIP This test needs root to run! Totals: pass:0 fail:0 xfail:0 xpass:0 skip:1 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
