The point of the test is to check the implementation of the
device_path_make_{major_minor|canonical) functions provided by
libsystemd-shared.

For that it checks a set of device nodes, among others /dev/random and
/dev/urandom.

I'm having a hard timinig blaming the test here, tbh. Having
/dev/urandom provide a defined behaviour is something that can be
expected from a sanely configured system.
