    gdb/testsuite: handle long filenames in gdb.base/startup-with-shell.exp
    
    I got a report of a failure from Linaro's CI testing for the test
    gdb.base/startup-with-shell.exp.
    
    Looking at the log I see this:
    
      (gdb) PASS: gdb.base/startup-with-shell.exp: startup_with_shell = on; run_args = *.unique-extension: inferior started
      print argv[1]
      $1 = 0xfffed978 "/home/tcwg-build/workspace/tcwg_gnu_4/abe/builds/armv8l-unknown-linux-gnueabihf/armv8l-unknown-linux-gnueabihf/gdb-gdb.git~master/gdb/testsuite/outputs/gdb.base/startup-with-shell/unique-file.unique-e"...
      (gdb) FAIL: gdb.base/startup-with-shell.exp: startup_with_shell = on; run_args = *.unique-extension: first argument expanded
    
    Notice that the value of $1 was truncated (indicated by the trailing
    ellipses), and as a result it isn't going to match the expected output
    pattern.
    
    Avoid this by adding a call to 'set print characters unlimited' which
    allows GDB to print strings of any length.
