test/fuzz: fix rpc, secret_connection and pex tests (#6190)

Browse Source 
* test/fuzz: fix rpc, secret_connection and pex tests

- ignore empty data in rpc
- provide correct IP in pex
- spawn a goroutine for Write and do multiple Read(s)

* test/fuzz: fix init in pex test

* test/fuzz: assign NewServeMux to global var

* test/fuzz: only try to Unmarshal if blob is not empty

* run fuzz tests for PRs which modify fuzz tests themselves

* test/fuzz: move MakeSwitch into init
