Ticket History #8493: Fix unaligned accesses in bt_split.c

Fix unaligned accesses in bt_split.c

In the libdb2 btree back end, splitting a page at an overflow key
could result in an unaligned access, causing a crash (and data
corruption) on platforms with strict alignment. This probably occurs
only rarely in practice.
