Add --no-index-cleanup and --no-truncate to vacuumdb.

Browse Source 
Both INDEX_CLEANUP and TRUNCATE have been available since v12, and are
enabled by default except if respectively vacuum_index_cleanup and
vacuum_truncate are disabled for a given relation.  This change adds
support for disabling these options from vacuumdb.
