Lower *_freeze_max_age minimum values.
The old minimum values are rather large, making it time consuming to
test related behaviour. Additionally the current limits, especially for
multixacts, can be problematic in space-constrained systems. 10000000
multixacts can contain a lot of members.
Since there's no good reason for the current limits, lower them a good
bit. Setting them to 0 would be a bad idea, triggering endless vacuums,
so still retain a limit.
While at it fix autovacuum_multixact_freeze_max_age to refer to
multixact.c instead of varsup.c.
