    [gdb/testsuite] Fix gdb.tui/completion.exp for local-remote-host-notty
    
    When running test-case gdb.tui/completion.exp with host board
    local-remote-host-notty and target board native-gdbserver, I get:
    ...
    FAIL: gdb.tui/completion.exp: completion of layout names: \
      tab completion (timeout)
    ...
    
    The test-case contains a few tests that do tab completion, which requires
    readline, which is unavailable with host board local-remote-host-notty.
    
    Fix this by adding the missing check for readline_is_used.
    
    Tested on x86_64-linux.
