[pbs-devel] [PATCH proxmox-backup] pxar: avoid including archive root's exclude patterns in .pxarexclude-cli

[Fabian Ebner <f.ebner@proxmox.com>]

The patterns from the archive root's .pxarexclude file are already present in
self.patterns when encode_pxarexclude_cli is called. Pass along the number of
CLI patterns and slice accordingly.
