runtime: add three new partial orders for lock ranking

Browse Source 
Two are associated with the new sysmon rank:  lockRankSysmon -> lockRankFin
(https://build.golang.org/log/07b0b8ee6ec9421d83699a1d850d9938390fb996)
and one I encountered during testing, lockRankSysmon -> lockRankWbufSpans

And another just seems not to have occurred before:  lockRankScavenge -> lockRankFin
(https://build.golang.org/log/07ba499b861fc93f527ef8514f5ba4c77086f4c4)
