    gdb/testsuite: avoid creating files in gdb/testsuite directory
    
    I spotted that the test gdb.dwarf2/dw2-using-debug-str.exp was
    creating an output file called debug_str_section in the root
    build/gdb/testsuite directory instead of using the
    build/gdb/testsuite/output/gdb.dwarf2/dw2-using-debug-str/ directory.
    
    This appears to be caused by a missing '$' character.  We setup a
    variable debug_str_section which contains a path within the output
    directory, but then when we build the objcopy command we use
    'debug_str_section' without a '$' prefix, as a result, we create the
    debug_str_section file.
    
    This commit adds the missing '$', the file is now created in the
    output directory.
