tiup not support package from release bot

I used /release in a PR and then got the released package. Then I used tiup patch to upgrade the cluster, but it failed:

[tidb@localhost ~]$ tiup cluster patch example tikv-server.tar.gz -R tikv
Starting component `cluster`: /home/tidb/.tiup/components/cluster/v0.4.9/cluster patch example tikv-server.tar.gz -R tikv

Error: entry tikv-server not found in package tikv-server.tar.gz

[tidb@localhost ~]$ tar tf tikv-server.tar.gz

I tried to patch with binary, it still failed:

[tidb@localhost ~]$ tiup cluster patch example bin/tikv-server -R tikv
Starting component `cluster`: /home/tidb/.tiup/components/cluster/v0.4.9/cluster patch example bin/tikv-server -R tikv

Error: exit status 2

Start by reproducing the tiup cluster patch commands with the release-bot archive and the bin/tikv-server path shown in the report. Trace how the cluster patch command locates package entries and handles these two inputs; done means both forms can patch the selected tikv role without the reported errors.
