    Fix gdb.tui/completion.exp test
    
    When I run it locally, the test gdb.tui/completion.exp test fails
    because of a timeout:
    
    Running /home/emaisin/src/binutils-gdb/gdb/testsuite/gdb.tui/completion.exp ...
    FAIL: gdb.tui/completion.exp: completion of layout names: tab completion (timeout)
    
    The problem seems to be this regex, which confirms that after doing
    layout<TAB>, "layout" is printed again after the gdb prompt:
    
      -re "^$input_line$"
    
    The problem is that there's a trailing space in the output after
    "layout".  Since the regex has an anchored end (the $), it doesn't
    match.  Adding a space fixes the test.
    
    gdb/testsuite/ChangeLog:
    
    	* gdb.tui/completionn.exp (test_tab_completion): Add space in
    	regex.
