bpf: Fix monitor aggregation for 'from-network'
bpf: Fix monitor aggregation for 'from-network'

Previously, we did not take into account 'from-network' sources in the
monitor aggregation logic check in `send_trace_notify()`, which was fine
because we rarely ever sent such events (limited to ipsec for instance).
However, since commit c470e28a82a9 we also use this in bpf_host which
suddenly means that any and all traffic from the network will trigger
monitor events, flooding the monitor output.

Fixes: 7a4b0beccbfe ("bpf: Add MonitorAggregation option")
Fixes: c470e28a82a9 ("Adds TRACE_TO_NETWORK obs label and trace pkts in to-netdev prog.")
