split proxmox-file-restore into its own crate

Browse Source 
This also moves a couple of required utilities such as
logrotate and some file descriptor methods to pbs-tools.

Note that the logrotate usage and run-dir handling should be
improved to work as a regular user as this *should* (IMHO)
be a regular unprivileged command (including running
qemu given the kvm privileges...)
