Merge #153405

153405: tracingpb: fix tag group formatting r=tbg a=stevendanna

This fixes trace entries that include literal %s:

    0.049ms 0.002ms === operation:/cockroach.roachpb.Internal/Batch
    gid:11120 _verbose:1 node:1 span.kind:server
    request:ReverseScan(Exclusive,Unreplicated)
    [/Table/100/"378826c2b6399273",/Table/100/"805b55ddf1552ea3")
    %s-locksnum:1 %s-lockswait:-2562047h47m16.853592s

It doesn't solve the unlikely value for lockswait.

Epic: none
Release note: None
