Fix upper limit for vacuum_cleanup_index_scale_factor
6ca33a88 sets upper limit for vacuum_cleanup_index_scale_factor to
DBL_MAX. DBL_MAX appears to be platform-dependent. That causes
many buildfarm animals to fail, because we check boundaries of
vacuum_cleanup_index_scale_factor in regression tests.
This commit changes upper limit from DBL_MAX to just "large enough"
limit, which was arbitrary selected as 1e10.
