Build flags read from env GO_BUILD_FLAGS are prepended to
flags in Makefile and sent to scripts/build.sh for building
executables (etcd, etcdctl & etcdutl).

When two members in a 5 member cluster are corrupted, and they
have different hashes, etcd will raise alarm for both members,
but the order isn't guaranteed. But if the two corrupted members
have the same hash, then the order is guaranteed. The leader
always raise alarm in the same order as the member list.

There is data race on `stop` channel. After verify write-timeout successfully,
the case won't wait for `blocker` to receive close signal from `stop` channel.
If the new `blocker`, which is to read-timeout verifier, get dial's result
immediately, the new `blocker` might fetch the message from `stop` channel
before old one and then close the connection, which causes that the
`conn.Read` returns `EOF` when it reads data.
How to reproduce this in linux devbox?
Use `taskset` to limit the test process in one-cpu.
```bash
cd ./client/pkg/transport
go test -c -o /tmp/test --race=true ./
taskset -c 0 /tmp/test -test.run TestWriteReadTimeoutListener -test.v -test.cpu 4 -test.count=10000 -test.failfast
```
To fix this, suggest to use seperate `stop` channel to prevent from data
race.

If quorum doesn't exist, we don't know which members data are
corrupted. In such situation, we intentionally set the memberID
as 0, it means it affects the whole cluster.
It's align with what we did for 3.4 and 3.5 in
https://github.com/etcd-io/etcd/issues/14849

The change did in https://github.com/etcd-io/etcd/pull/14824 fixed
the test instead of the product code. It isn't correct. After we
fixed the product code in this PR, we can revert the change in
that PR.

When the leader detects data inconsistency by comparing hashes,
currently it assumes that the follower is the corrupted member.
It isn't correct, the leader might be the corrupted member as well.
We should depend on quorum to identify the corrupted member.
For example, for 3 member cluster, if 2 members have the same hash,
the the member with different hash is the corrupted one. For 5 member
cluster, if 3 members have the same same, the corrupted member is one
of the left two members; it's also possible that both the left members
are corrupted.

1. Add field `HashRevision` into `HashKVResponse`;
2. Display the new field when executing `etcdctl endpoint hash`.
