solaris: unbundle mkstemp and mkdtemp.

* configure: Solaris 10 doesn't have mkdtemp, so we detect
it separately from mkstemp, which Solaris 10 does have,
producing HAVE_MKSTEMP and MAKE_MKDTEMP config.h symbols.

* stream.c (mkdtemp_wrap): Separately surround
with #if HAVE_MKDTEMP.
(mkstemp_wrap): Reduce scope of #if HAVE_MKSTEMP only around
this function. Bugfix here: in the #else case
of #if HAVE_MKSTEMPS, we are calling the mkstemps function
instead of mkstemp.
