    gdb: remove unused includes from dwarf2read.c
    
    include-what-you-use says:
    
    ../../../src/binutils-gdb/gdb/dwarf2read.c should remove these lines:
    - #include <ctype.h>  // lines 67-67
    - #include <sys/stat.h>  // lines 59-59
    - #include <sys/types.h>  // lines 83-83
    - #include <cmath>  // lines 88-88
    - #include <forward_list>  // lines 90-90
    - #include <set>  // lines 89-89
    - #include <unordered_set>  // lines 85-85
    - #include "completer.h"  // lines 60-60
    - #include "expression.h"  // lines 44-44
    - #include "gdbsupport/byte-vector.h"  // lines 78-78
    - #include "gdbsupport/filestuff.h"  // lines 71-71
    - #include "gdbsupport/gdb_unlinker.h"  // lines 74-74
    
    After a quick glance, that makes sense, so this patch removes them.
