Bash 2.05 'configure' unnecessary double-check for 'wait3'

When I configure Bash 2.05, it outputs this:

checking for wait3 that fills in rusage... no
...
checking for wait3... yes

The second check overrides the result of the first check, so the first
check is redundant.  I looked at the code, and Bash never needs the
rusage part of wait3, so the first check is redundant anyway.

Here is a patch.

        * configure.in (AC_FUNC_WAIT3): Remove: it was not used, since a later
        `AC_CHECK_FUNC(wait3, AC_DEFINE(HAVE_WAIT3))' overrode the result.
        Bash doesn't need the special feature of AC_FUNC_WAIT3 anyway.
