configure: update ubcl with newer help macro

with recent autoconf tool chain autogen.pl emits a warning
mess when processing the ompi_check_ubcl.m4 file:

autoreconf: running: /opt/homebrew/Cellar/autoconf/2.71/bin/autoconf --include=config --include=config/oac --force
configure.ac:1209: warning: The macro `AC_HELP_STRING' is obsolete.

This patch fixes that.
