tests: enable Github action

With this patch, four kinds of tests are triggered when there is a
pull request created in a Github kdump-uitls repo,
   - format check using shfmt
   - static analysis using shellcheck
   - ShellSpec unit tests (test cases in spec/)
   - integration tests (tests cases in tests/)
