Subject: filter API: Fix Python bindings and multi_usrp calls

This fixes the following issues:
- The Python bindings did not declare parents for the various filter
  object classes properly. This meant that set_?x_filter wouldn't work,
  because the user would pass a specific type (e.g., analog_filter_lp),
  but the class would not recognize it as a filter_info_base.
- In multi_usrp.cpp, filter names are also property tree paths to make
  them unique. However, the setters and getters for filters would then
  prepend the FE path again, thus breaking those calls.
