change tape drive lock path

Browse Source 
New kernel has stricter checks on tmpfs with stick-bit on directories, so some
commands (i.e. proxmox-tape changer status) fails when executed as root, because
permission checks fails when locking the drive.

This patch move the drive locks to /run/proxmox-backup/drive-lock.

Note: This is incompatible to old locking mechmanism, so users may not
run tape backups during update (or running backup can fail).
