qa/cephfs: don't strip any whitespace for get_shell_stdout

Whitespace is not removed from the end of the stdout returned by the
method get_ceph_cmd_stdout(). Follow the same policy here since it is
better to not do so (this whitespace can be useful, when copying Ceph
auth keyrings from stdout to a file) and also for sake of uniformity of
interfaces.
