osd: populate the trim_thru epoch using MOSDMap.oldest_map

instead of filling MOSDMap with the local oldest_map, we share
the maximum MOSDMap.oldest_map received so far with peers. That
way one OSD's failure to trim won't prevent it from sharing with
others that they are allowed to trim.

Fixes: #13990

(cherry picked from commit 9789c29fe0f82b236703f7ae4d356251fde3a46f)

Conflict: use atomic_t instead of std::atomic<>
