    evdev: use a prometheus-safe label for ev_sysctl_tree
    
    Prometheus doesn't allow spaces, let's normalize this to what we use
    elsewhere for consistency.  The sysctl exporter could probably do this
    itself, but let's decouple that from the immediate problem: matching the
    label between the exported data and in-tree is nice for greppability.
