* Add nil check for sshd config file
This fixes#1778. There was a issue where if the user did not have read
permissions on /etc/ssh/sshd_config it would error out on the empty?
check. The fix here is to also look for nil on the file content. Along
with this I refactored the inspec file empty? check as it does not exist
and was also erroring during my testing.

`must_equal nil` will fail in MiniTest 6. Changing those to `must_be_nil`
quiets down all the warnings we currently see and preps us for Minitest 6.
