Subject: gdb/python: implement DisassemblerResult.__str__ method

Add the DisassemblerResult.__str__ method.  This gives the same result
as the DisassemblerResult.string attribute, but can be useful
sometimes depending on how the user is trying to print the object.

There's a test for the new functionality.
