MapEverywhere() misses %zpkg package

I ran `##class(SourceControl.Git.API).MapEverywhere()` to make the module available in all the namespaces in my instance. When I went to edit an interop production, I received this exception popup:


I went back to my terminal session to dump the session variables and noticed this:

```ObjectScript
%objlasterror="0 S¥ PackageSourceControl.Git%ALL$%SYS(e^Exists+5^Config.CommonMapMethods.1^
2+e^ClassMapping+4^
%Installer.Installer.1^1Dd^

MapEverywhere+8^|"ENSGLOBAL"|SourceControl.Git.Installer.1^1:e^
MapEverywhere+1^|"ENSGLOBAL"|SourceControl.Git.API.1^1e^^^0"
```

While this method did map the `SourceControl.*` package to my other namespaces, maybe it also needs to map `%zpkg.isc.*`?

Additionally, the `MapEverywhere()` definitions should really be annotated with `As %Status`. It is inconsistent that they don't have this.
