[PATCH 1/5] selftests/landlock: fix return condition on create_directory

[Jeffrey Bencteux <jeff@bencteux.fr>]

If path exists when calling create_directory() in tests, i-e. when
mkdir() return with EEXISTS, directory creation fails. This patch
fixes it by allowing create_directory to use eventual existing
directories.
