If selftests are run as root, then execute the unprivileged checks as
well. This switch from 243 to 368 tests.

The test numbers are suffixed with "/u" when executed as unprivileged or
with "/p" when executed as privileged.

The geteuid() check is replaced with a capability check.

Handling capabilities requires the libcap dependency.
