selftest: Add a python blackbox test for some misc (widelink) DFS tests

On master attempting to chdir into a nested dfs link

e.g. cd dfslink (works)
     cd dfslink/another_dfslink (fails)

[1] Add a test for this scenario (nested chdir)
[2] Add test for enumerating a dfs link in root of dfs share
[3] Add a test to check case insensitive chdir into dfs link on widelink
  enabled share

Add knownfails for tests 1 and 3

(cherry picked from commit 7f1de90f72d6e8287aec6ab1d9f7776b7df624e5)

[noel.power@suse.com backported to Samba 4.19 changed knownfails because
  test_ci_chdir doen't fail in 4.19 but test_enumerate_dfs_link does]
