Subject: [PATCH 1/2] udev-test: fix test skip condition

When there is a failure to setup the environment, the following happens:

1. Command "./test-udev check" exits with non-zero code.
2. Perl function "system" returns the code.
3. The code is evaluated as true by Perl.

Then we stop the test.

Subject: [PATCH 2/2] udev-test: fix missing directory test/run

Fixes the following error:

    Failed to mount test /run: No such file or directory

By the time command "./test-udev check" calls function "fake_filesystems",
directory "test/run" must be present.
