build: add debugging targets and improve Makefile structure (#215)

- Introduced new Makefile targets for debugging: `dlv`, `kyanos-debug`, and `remote-debug`.
- The `dlv` target sets executable permissions and starts the debugger in headless mode.
- The `kyanos-debug` target builds the project with specific flags for debugging.
- The `remote-debug` target depends on building BPF and the `kyanos-debug` target, streamlining the debugging process.
