bufmgr: Remove buffer-write-dirty tracepoints
The trace point was using the relfileno / fork / block for the to-be-read-in
buffer. Some upcoming work would make that more expensive to provide. We still
have buffer-flush-start/done, which can serve most tracing needs that
buffer-write-dirty could serve.
