    [gdb/testsuite] Fix gdb.python/py-failed-init.exp with python 3.15
    
    On Fedora Rawhide aarch64-linux, I ran into:
    ...
    builtin_spawn $build/gdb/gdb -nw -nx -q -iex set height 0 -iex set width 0 \
      -data-directory $build/gdb/data-directory -iex set interactive-mode on
    WARN: Could not find the standard library directory! The Python 'home'
    directory was set to 'foo', is this correct?
    Error occurred computing Python error message.
    $build/gdb/gdb: warning:
    Could not load the Python gdb module from
    `$build/gdb/data-directory/python'.
    Limited Python support is available from the _gdb module.
    Suggest passing --data-directory=/path/to/gdb/data-directory.
    (gdb) set height 0
    (gdb) set width 0
    (gdb) dir
    Reinitialize source path to empty? (y or n) y
    Source directories searched: $cdir:$cwd
    (gdb) dir $src/gdb/testsuite/gdb.python
    Source directories searched:
    $src/gdb/testsuite/gdb.python:$cdir:$cwd
    (gdb) python print (1)
    1
    (gdb) FAIL: $exp: gdb-command<python print (1)>
    quit
    Exception ignored on threading shutdown:
    Traceback (most recent call last):
      File "<string>", line 2, in <module>
    ModuleNotFoundError: No module named 'importlib'
    PASS: gdb.python/py-failed-init.exp: quit
    ...
    
    The ModuleNotFoundError reported after quit originates from
    gdbpy_initialize_gdb_readline.  I've filed a PR about this [1].
    
    The test-case tries to break python:
    ...
    save_vars { env(PYTHONHOME) } {
        setenv PYTHONHOME foo
        clean_restart
    }
    ...
    enough to get it to this point:
    ...
    gdb_test "python print (1)" \
        "Python not initialized"
    ...
    but apparently, that doesn't work anymore in this python version:
    ...
    $ python --version
    Python 3.15.0b4
    ...
    
    Update the test-case by simply accepting the output.
