mktemp: fix bug with -q and closed stdout
If stdin or stdout is closed, then freopen(,stderr) can violate
the premise that STDERR_FILENO==fileno(stderr), which in turn
breaks mktemp -q.
* bootstrap.conf (gnulib_modules): Add freopen-safer.
* src/mktemp.c (includes): Use stdio--.h.
* tests/misc/close-stdout: Enhance test to catch bug.
