It' unsafe to replace into patch dir if there are dynamic libraries

Bug Report

If runtime needs dynamic libraries, overwriting binaries by cmd tar directly may cause unexpected behavior.

Like https://github.com/pingcap/tiup/blob/ca49c7e8f57bccc5ff79520d1f5a5481d62364b1/pkg/cluster/task/install_package.go#L50

2 options:

• Remove target binaries first before installing.
• Stop services(like tiflash server) before installing.
