tests: endpoint: fix valgrind uninit warning

Browse source 
Previously, valgrind was warning that

  Syscall param sendmsg(msg.msg_iov[0]) points to uninitialised byte(s)

this was caused by uninitialized values being serialized for IPC.
Specifically, not all members of the `pw_endpoint_info` struct were
initialized, which caused uninitialized bytes to end up in the IPC
buffers due to the `pw_endpoint_emit_info()` in `endpoint_add_listener()`.

Fix that by initializing the missed `id` and `flags` members.
