What problem does this PR solve?

Issue Number: close #334

Problem Description: G10 (sink_hang + sigstop) run more than 25 minutes

What is changed and how does it work?

• Skip check_count 2 "pd" after kill -19 pd-server. See https://github.com/tikv/migration/issues/334#issuecomment-1425997573

• Prolong sleep duration of check_sync_diff As the original 1s is not enough. See https://do.pingcap.net/jenkins/blue/organizations/jenkins/tikv%2Fmigration%2Fpull_integration_test/detail/pull_integration_test/77/pipeline/336.

• Add timeout for lsof as lsof has chances to take a long time due to unknown reason (maybe container environment ?).

• Other polish

To reviewers

Please follow these principles to check this pull requests:

• Concentration. One pull request should only do one thing. No matter how small it is, the change does exactly one thing and gets it right. Don't mix other changes into it.
• Tests. A pull request should be test covered, whether the tests are unit tests, integration tests, or end-to-end tests. Tests should be sufficient, correct and don't slow down the CI pipeline largely.
• Functionality. The pull request should implement what the author intends to do and fit well in the existing code base, resolve a real problem for TiDB/TiKV users. To get the author's intention and the pull request design, you could follow the discussions in the corresponding GitHub issue or internal.tidb.io topic.
• Style. Code in the pull request should follow common programming style. (For Go, we have style checkers in CI). However, sometimes the existing code is inconsistent with the style guide, you should maintain consistency with the existing code or file a new issue to fix the existing code style first.
• Documentation. If a pull request changes how users build, test, interact with, or release code, you must check whether it also updates the related documentation such as READMEs and any generated reference docs. Similarly, if a pull request deletes or deprecates code, you must check whether or not the corresponding documentation should also be deleted.
• Performance. If you find the pull request may affect performance, you could ask the author to provide a benchmark result.
