Subject: Add optional command line parameter: archisobasedir

When remastering the image onto a USB volume, you might want to reuse
an existing partition without filling the root with lots of archiso
files. The archisobasedir parameter allows to specify a new root
directory, isomounts and all images will be searched in this directory.
