Separate local db directory creation and db write

Changelogs and install files were getting extracted into the local
db folder before it was manually created.  This created issues for
uses with 0077 umasks and was highlighted with the new sudo handling
of umasks (FS#12263).

This moves the local db creation to its own function which is called
before the start of package archive extraction.  Also, added a check
that the folder is actually created.
