atrace.rc: fix duplicated block due to automerging

My aosp/2449540 was trying to sync aosp and internal state, but the
diffs lined up in a way that some internal branches got a duped
boottrace block. Resolve that manually with a merged-in spec with an
internal/master change-id as that branch and its downstream is
undamaged. Branches in question:
