    [gdb/testsuite] Fix gdb.dwarf2/dw2-unspecified-type-foo.c with -m32
    
    When running test-case gdb.dwarf2/dw2-unspecified-type-foo.c with target board
    unix/-m32, I run into:
    ...
    (gdb) PASS: gdb.dwarf2/dw2-unspecified-type.exp: ptype foo
    p ((int (*) ()) foo) ()^M
    $1 = -135698472^M
    ...
    
    Add the missing "return 0" in foo, which fixes this.
    
    Tested on x86_64-linux.
