    random: remove unused tracepoints

    These explicit tracepoints aren't really used and show sign of aging.
    It's work to keep these up to date, and before I attempted to keep them
    up to date, they weren't up to date, which indicates that they're not
    really used. These days there are better ways of introspecting anyway.
