ipatests: fix / permissions to allow ssh with private key

The test test_ssh_key_connection is performing a ssh login
with a private and this command may fail if the root directory
does not have the right permissions on the ssh server
(see https://access.redhat.com/solutions/6798261)

Ensure that / has 755 before launching the test.
