TESTS: test_0017_filesldap is missing staticmethod

* @staticmethod is required for this method.
* setup_sssd_krb is added since krb configuration is required for this test.
* The first sssctl can make the pipe number increase (usually +2), so run
the first sssctl before collecting /tmp/before_count.
