[pbs-devel] [PATCH proxmox-backup 1/2] fix #4578: use log crate for pxar create logging

["Fabian Grünbichler" <f.gruenbichler@proxmox.com>]

since proxmox-backup-client is used in cron jobs and similar automated
fashions, PBS_LOG= should control the output..

came up a few times in the forum already, follow up to the switch to log
