Add SCM_OPN to mode bits when making ports

Browse source 
* libguile/ports.c (scm_c_make_port_with_encoding): Add SCM_OPN to mode
  bits, so that users don't have to.
  (scm_i_mode_bits_n):
* libguile/print.c (scm_simple_format)
* libguile/r6rs-ports.c (make_bytevector_input_port)
  (make_custom_binary_input_port, make_bytevector_output_port)
  (make_custom_binary_output_port, make_transcoded_port)
* libguile/strports.c (scm_object_to_string, scm_open_input_string)
  (scm_open_output_string, scm_c_read_string): Remove now-unneeded
  SCM_OPN mentions.
