Remove HEAP_ALIGN_LOG setting in configure.ac for OpenBSD/MirOS

Browse source 
The ruby setting was renamed to HEAP_PAGE_ALIGN_LOG, but the
configure.in (now configure.ac) file was not updated, so the
setting had no effect.  The configure setting is unnecessary
after OpenBSD 5.2 and MirOS has been discontinued (with the last
release being over 10 years ago), so it is better to just remove
the related configure setting.

Fix [Bug #13438]
From: Jeremy Evans <code@jeremyevans.net>
