mkstemps: ensure declaration

[Bruno Haible]

On MacOS X 10.5, mkstemps is declared in <unistd.h>, not in <stdlib.h>. This
leads to a failure in a testdir created by
  $ ./gnulib-tool --create-testdir --dir=... --with-tests --with-c++-tests 
mkstemps

g++ -DHAVE_CONFIG_H -I.  -DGNULIB_STRICT_CHECKING=1 -I. -I. -I.. -I./.. 
-I../gllib -I./../gllib -Wall   -MT test-stdlib-c++.o -MD -MP -MF 
.deps/test-stdlib-c++.Tpo -c -o test-stdlib-c++.o test-stdlib-c++.cc
../gllib/stdlib.h:731: error: '::mkstemps' has not been declared
../gllib/stdlib.h:732: error: 'mkstemps' was not declared in this scope
../gllib/stdlib.h:732: error: invalid type in declaration before ';' token
make[4]: *** [test-stdlib-c++.o] Error 1

This fixes it:

        mkstemps: Ensure declaration on MacOS X 10.5.
        * lib/stdlib.in.h: Include <unistd.h> when mkstemps is requested.
        * doc/glibc-functions/mkstemps.texi: Document header file problem on
        MacOS X.
