[pbs-devel] [RFC PATCH proxmox-backup 2/2] tape/inventory: fix the tape tests as user by mocking the lock

[Dominik Csapak <d.csapak@proxmox.com>]

locking during the tests as regular user failed because we try to
chown to the backup user (which is not always possible).

Instead, do not lock at all, by mocking the 'open_backup_lockfile' with
an empty struct that implements the locking trait
