Subject: [PATCH] fix(linux): stop marking the terminal host scope
 ManagedOOMPreference=avoid (#32935)

uresourced before 0.5.5 answers every attribute write on the scope's cgroup by
re-setting its CPU and IO weights, which makes systemd rewrite the oomd xattr
again. The loop pins systemd --user and eventually stops it starting new
terminals. Per-terminal scopes already keep oomd from taking every terminal.
