minor timezone fix for autoconf.texi

[Paul Eggert]

A note from Akim about coreutils/lib/tempname.c prompted me to find a
minor problem in the documentation about AC_HEADER_TIME.  `struct
timezone' is completely obsolete now, so we shouldn't be suggesting it
to Autoconf users.

        * doc/autoconf.texi (Particular Headers): Remove obsolete
        reference to `struct timezone' in the description of
        AC_HEADER_TIME.
