gdb/python: missing PyObject_IsTrue error check in bppy_init

As with the previous two commits, this commit fixes a location where
we called PyObject_IsTrue without including an error check, this time
in bppy_init.

The 'qualified' argument is supposed to be a bool, the docs say:

  The optional QUALIFIED argument is a boolean that allows
  interpreting the function passed in 'spec' as a fully-qualified
  name.  It is equivalent to 'break''s '-qualified' flag (*note
  Linespec Locations:: and *note Explicit Locations::).

It's not totally clear that the only valid values are True or False,
but I'm choosing to interpret the docs that way, and so I've added a
PyBool_Type check during argument parsing.  Now, if a non-bool is
passed the user will get a TypeError during argument parsing.  I've
added a test to cover this case.

This is a potentially breaking change to the Python API, but hopefully
this will not impact too many people.  I've added a NEWS entry to
highlight this change.
