optimize(bpf): Delete tgid_pname_map

[jschwinger233]

Background

tgid_pname_map 只是用在 cookie_pid_map update 失败时的 fallback：

1. cookie_pid_map update 失败是少见的情况，在正常场景下不需维护 tgid_pname_map。
2. 就算是 cookie_pid_map update 失败，先 _update_map_elem_by_cookie() 里 tgid_pname_map[pid] = val 再在上层函数 update_map_elem_by_cookie() 里读 tgid_pname_map[pid] 也是多此一举，一个指针传递就行了，无需用 map。

这个 PR 直接删去了 cookie_pid_map 同时维持了 fallback 逻辑，减小了内核内存消耗，整整 8192 * (4 + 16) = 163840 bytes = 0.16384 Mb 呢！同时省去了 wan 代理时对每个 socket 的一次 map 操作，提升全局性能。
