portpkg: support deleting files and directories before building the pkg.

This feature is useful when one wants to shrink the size of the pkg's
and mpkg's for deployment to Macs that will not be used for
development.  One large mpkg was observed to shrink from 504 MB to 271
MB, where we are disting the mpkg using Munki to hundreds of Macs.
