pycriu: Fix self-dump failure with explicit PID

Browse source 
When `opts.pid` is explicitly set to `os.getpid()`, `pycriu` fails to
daemonize the `criu` process. This causes `criu` to run as a child of
the dumped process, leading to the error "The criu itself is within
dumped tree".

This can be fixed by modifying `_send_req_and_recv_resp` to check if the
target PID matches the current process PID. If so, it enables daemon
mode, ensuring `criu` is detached and the dump succeeds.
