landlock: Clarify IPC scoping documentation
* Clarify terminology
* Stop mixing the unix(7) and signal(7) aspects in the explanation.

Terminology:

* The *IPC Scope* of a Landlock domain is that Landlock domain and its
  nested domains.
* An *operation* (e.g., signaling, connecting to abstract UDS) is said to
  be *scoped within a domain* when the flag for that operation was set at
  ruleset creation time.  This means that for the purpose of this
  operation, only processes within the domain's IPC scope are reachable.
