LU-14432 configure.ac: fix AC_PREREQ

AS_HELP_STRING was introduced in autoconf 2.58
requiring autoconf 2.69 is not necessary and it breaks
several builds in our Jenkins.

Change required autoconf to 2.59 just to be safe.

Fixes: 8c9e2921 ("configure.ac: convert all help strings to use AS_HELP_STRING")
