rgw: Fix truncated ListBuckets response.

Commit 54b470facffe8251dc37b2020e771d4d061cb2ae caused s3:ListBuckets to
return a maximum of 1000 buckets by default as it removed the truncation
detection from this code. We can fix this by simply setting
RGWListBuckets::is_truncated after querying for each batch of buckets.
