isr_admin: makeparcel: Don't copy /etc/openisr/skel into cfg tarball

- No longer copy the contents of /etc/openisr/skel into the cfg tarball.
Populating the cfg tarball is no longer the responsibility of isr_admin
(except for the "suspended" flag file); it is now the client's job.  So,
it no longer makes sense for the server administrator to provide files
to prepopulate the cfg tarball.
