rtp{vorbis,theora}{pay,depay}: Cosmetic cleanup

* use g_list_free_full(), don't iterate elements maually when freeing
* call gst_rtp_*_pay_clear_packet(), don't duplicate its code
* use gst_buffer_unref() to clarify that it is buffers being released,
  instead of refering directly to gst_mini_object_unref()

Fixes https://bugzilla.gnome.org/show_bug.cgi?id=755277
