bad code in fs-traverse update in portarchive.tcl

[david.osguthorpe@…]

Since 1.8.0 at least (but not at 1.7.0) the original 1.7.0 find code in archive_main in portarchive.tcl

foreach fullpath [exec find $destpath ! -type d] {
...
}

was replaced by an fs-traverse call

        fs-traverse fullpath $destpath {
            if {[file isdirectory $fullpath]} {
                continue
            }
       ....
      }

this code terminates immediately as the first fullpath is a directory which is skipped and hence the contents of the directory are not scanned - ... is never executed for anything

this means since 1.8.0 all +CONTENTS files in archives are incorrect as they do not have a file list

fixups are

        fs-traverse -depth fullpath $destpath {
            if {[file isdirectory $fullpath]} {
                continue
            }
       ....
      }

or

        fs-traverse fullpath $destpath {
            if {![file isdirectory $fullpath]} {
                ...
            }
      }
