Dmitry V. Levin 212a444bdc decode_open: print the mode argument when O_TMPFILE flag is set
O_TMPFILE reqires the mode argument (just like O_CREAT), so print it.

* open.c (STRACE_O_TMPFILE): New macro.
(decode_open): Print the mode argument when O_TMPFILE flag is set.
* tests/open.c (main): Check it.
Fixes RH#1377846.
