Use expand-full switch with pkgutil

[marczak]

The (undocumented) expand-full switch will expand all components and better drill down into distribution-style packages.

Addendum: I don't recall where this switch appeared, so, this could break the processor on much older OS Versions (10.11-era and earlier).

1. Please swap this to the dev branch.
2. What is this actually doing? What's different about the expanded output compared to before? Showing the results of an actual recipe run could help. I don't really have any context on what this is actually solving or accomplishing.

Ah, sure. --expand-full will also expand a package's payload. Here's an example from distribution-style package:

with --expand:

% ls -la

same package with --expand-full:

% ls -la

drwxr-xr-x  7 marg  staff    224 Oct  6 17:26 Scripts

Notice that in the second example, Payload is now a directory, requiring no further expansion. In the case of this package:

% ls -la Payload/

In an AutoPkg recipe, one can now immediately use the results for repackaging.
