Fix race condition in orphan-inodes test

Make sure that the orphan scanners can see deletions after forced unmounts
by waiting for reclaim_open_log_tree() to run on each mount; and waiting for
finalize_and_start_log_merge() to run and not find any finalized trees.

Do this by adding two new counters: reclaimed_open_logs and
log_merge_no_finalized and fixing the orphan-inodes test to check those
before waiting for the orphan scanners to complete.
