lib: Reclaim aged leaked ssm pool blocks
The reclaim_pid_from_sc() function reaped any block allocated with
refcount from a dead PID, but cross-process hand-offs can leave a
block briefly allocated by the producer while a live consumer still
holds it. This skips reclaim within SSM_POOL_RECLAIM_AGE_S (default
60s) so in-flight hand-offs survive a producer crash.
