futils_mktmp: don't use umask. Previously, we were using `umask(mask = umask(0))` to fetch the current umask in order to apply it to the desired mode, but this is broken in the presence of threads. There is no portable way to directly fetch umask without mutating it. Instead, add a reimplementation of mkstemp that uses a passed-in mode, instead of explicitly chmodding to 0600 like POSIX requires of mkstemp. Fixes: jmgao/pore#46
