If selftests are run as root, then execute the unprivileged checks as
well. This switch from 240 to 364 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 require the libcap dependency.
