Disable E106 & E208 for now

E106 rejects roles with '-' in their names, which is important
for collections, but these aren't collections.

Also ansible-lint throws an undocumented error "E208 File permissions not
mentioned" that looks too aggressive, for example it complains IMHO
wrongly about:

roles/add-build-sshkey/tasks/remote-linux.yaml [E208] File
permissions not mentioned
roles/add-build-sshkey/tasks/remote-linux.yaml:14: [E208] File
permissions not mentioned
roles/add-build-sshkey/tasks/remote-linux.yaml:20: [E208] File
permissions not mentioned
roles/add-build-sshkey/tasks/remote-linux.yaml:27: [E208] File
permissions not mentioned

Disable it for now until ansible-lint is fixed - and the real problems
in zuul-jobs are fixed.

https://github.com/ansible/ansible-lint/pull/949 fixes the false
positives. Once that is merged and a new release is out, we should
revert and fix the real problems.
