librelad 7acfdabbac refactor(de-sudo): backup subsystem data ops via runFileOp/runFileWrite
The backup engine already drops to the backup user (sudo -E -u
$docker_install_user) and backupLocationOwner == $docker_install_user, which is
exactly what runFileOp/runFileWrite resolve to in both modes. So convert the
raw-sudo data ops (mkdir/chmod/rm/find/cat/grep/mv/chown/tee on backup repos,
location configs, keys, manifests) to runFileOp/runFileWrite — creating files
as the owner directly, no root chown. backup_verify creates its scratch as the
backup user (runFileOp mktemp) instead of chown-after. Binary installs
(kopia tar/install, borg dnf) -> runSystem. The 44 sudo -u engine drops stay
(already least-privilege; the scoped sudoers will grant them).
