PATCH: small compilation cleanup for utils.c

["John T. Guthrie" <guthrie@counterexample.org>]

Hello all,

This is a very small patch to clean up compilation on RedHat Linux.  (And,
I believe on most anything that uses GLIBC >= 2.0, but I'm not certain of
that.)  When compiling on RedHat Linux 8.0, I get the compilation complaint:

utils.o: In function `gettempname':
utils.o(.text+0x1b1a): the use of `mktemp' is dangerous, better use `mkstemp'

This patch fixes that for systems that have mktemp(), but not _mktemp().  I
saw that configure was testing for both mkstemp() and _mktemp(), but the code
only used _mktemp().  I don't know whether the test for HAVE_MKSTEMP should
come before or after the test for HAVE__MKTEMP, so let me know if there is a
different preferred order.
