    gdb/testsuite: fix failure in gdb.python/py-unwind.exp
    
    A potential test failure was introduced with commit:
    
      commit 6bf5f25bb150c0fbcb125e3ee466ba8f9680310b
      Date:   Wed Mar 8 16:11:30 2023 +0000
    
          gdb/python: make the gdb.unwinder.Unwinder class more robust
    
    In this commit a new test was added, however the expected output
    pattern varies depending on which Python version GDB is linked
    against.
    
    Older versions of Python result in output like this:
    
        (gdb) python global_test_unwinder.name = "foo"
        Traceback (most recent call last):
          File "<string>", line 1, in <module>
        AttributeError: can't set attribute
        Error while executing Python code.
        (gdb)
    
    While more recent versions of Python give a similar, but slightly more
    verbose error message, like this:
    
        (gdb) python global_test_unwinder.name = "foo"
        Traceback (most recent call last):
          File "<string>", line 1, in <module>
        AttributeError: can't set attribute 'name'
        Error while executing Python code.
        (gdb)
    
    The test was only accepting the first version of the output.  This
    commit extends the test pattern so that either version will be
    accepted.
