Vitaly Chikunov 8b65ef5ad4 selftests/mm: Fix build with _FORTIFY_SOURCE
Add missing flags argument to open(2) call with O_CREAT.

Some tests fail to compile if _FORTIFY_SOURCE is defined (to any valid
value) (together with -O), resulting in similar error messages such as:

  In file included from /usr/include/fcntl.h:342,
                   from gup_test.c:1:
  In function 'open',
      inlined from 'main' at gup_test.c:206:10:
  /usr/include/bits/fcntl2.h:50:11: error: call to '__open_missing_mode' declared with attribute error: open with O_CREAT or O_TMPFILE in second argument needs 3 arguments
     50 |           __open_missing_mode ();
        |           ^~~~~~~~~~~~~~~~~~~~~~

_FORTIFY_SOURCE is enabled by default in some distributions, so the
tests are not built by default and are skipped.

open(2) man-page warns about missing flags argument: "if it is not
supplied, some arbitrary bytes from the stack will be applied as the
file mode."
