    [gdb/testsuite] Handle missing curses in gdb.python/py-missing-debug.exp
    
    On a system with python 3.6, module gdb.missing_debug imports module curses,
    so when running test-case gdb.python/py-missing-debug.exp on a system without
    that module installed, we run into:
    ...
    (gdb) source py-missing-debug.py^M
    Python Exception <class 'ImportError'>: Module 'curses' is not installed.^M
    Use:^M
      sudo zypper install python36-curses^M
    to install it.^M
    Error occurred in Python: Module 'curses' is not installed.^M
    Use:^M
      sudo zypper install python36-curses^M
    to install it.^M
    (gdb) FAIL: gdb.python/py-missing-debug.exp: source python script
    ...
    
    Fix this by issuing UNSUPPORTED instead, and bailing out.
    
    Tested on x86_64-linux.
