nbtree README: move VACUUM linear scan section.

Discuss VACUUM's linear scan after discussion of tuple deletion by
VACUUM, but before discussion of page deletion by VACUUM. This
progression is a lot more natural.

Also tweak the wording a little. It seems unnecessary to talk about how
it worked prior to PostgreSQL 8.2.
