tests: rename deleted_standalone_unix to del_standalone_un

The directory that the tests run in on jenkins is:

/var/lib/jenkins/workspace/CRIU/CRIU-restore-sibling/criu-dev/test/zdtm/static

which makes the whole path too long. This commit makes the whole path:

/var/lib/jenkins/workspace/CRIU/CRIU-restore-sibling/criu-dev/test/zdtm/static/del_standalone_un.test/sock

which is 105 chars, less than 108 of sun_path.

Closes #191
