Don't truncate heap when VACUUM's failsafe is in effect.
It seems like a good idea to bypass heap truncation when the wraparound
failsafe mechanism (which was added in commit 1e55e7d1) is in effect.
Deliberately don't bypass heap truncation in the INDEX_CLEANUP=off case,
even though it is similar to the failsafe case. There is already a
separate reloption (and related VACUUM parameter) for that.
