Fix a compile error in nacl_security_tests on some versions
of gcc.

Some versions of gcc give the following compilation error: /usr/include/bits/fcntl2.h:51: error: call to ‘__open_missing_mode’ declared with attribute error: open with O_CREAT in second argument needs 3 arguments
make: *** [out/Release/obj.target/nacl_security_tests/chrome/test/nacl_security_tests/commands_posix.o] Error 1

So provide a third argument (the permissions of the file if created).
