[PATCH 0/2] selftests: capabilities: convert to TAP13 ksft framework

[Shuah Khan <shuahkh@osg.samsung.com>]

This patch series consists of a fix to run a skipped test and converting
to TAP13 ksft framework. I found this skipped test while I was testing the
TAP13 changes.

Next up is converting err() and errx() to appropriate ksft_ routines as
needed and appropriate. The output from non-root user run reflects the
pending work.

Output after conversion when root runs the test:
------------------------------------------------
