open: Add support for O_TMPFILE
Since Linux 3.11, O_TMPFILE allows to create unnamed files that can be linked later on. It is internally defined as (O_TMPFILE | O_DIRECTORY) to make it fail on old kernels. Copying definitions from glibc for O_TMPFILE is not enough to support O_TMPFILE; The open() wrapper also need to pass the mode when the flag contains O_TMPFILE, otherwise, it will pass mode 000 which will succeed but yield unexpected results. openat() is curiously not affected since it passes the mode unconditionally.. Signed-off-by: Nicolas Cavallari <nicolas.cavallari@green-communications.fr>
