Several tests require complete file lists in order to provide accurate
results.  These can be non-obvious.  Adding missing parent directories
helps insure the integrity of tests against human error.  Filling in
parent directories also allows us to check that file lists are actually
valid.

There didn't seem to be a good place to do this that was always
guaranteed to be run, so this adds a finalize() function to packages
that will always be run before the package is actually used to allow for
this type of tidying.

Fixes FS#30723
