3b390793b9 Fix bug in macro that was masked by old evttype checking
It turns out that the macro inbound_outbound had a logical bug where
joining the beginning and end of the macro with "or" led to the macro
matching all event types by accident.

Most of the time this isn't harmful but it turns out some trace files
will do operations on inet connection fds like "dup", and those get
mistakenly picked up by this macro, as the fd for the event does
happen to be a network connection fd.

This fixes the macro to only match those event types *and* when the fd
is a inet connection fd.

abc79fb548 update(rules): revert exceptions in default ruleset
Exceptions have been introduced in commit 64a231b962
The feature itself is very useful for more complex environments where
the simple conditions are difficult to handle.
However, many users reported that they find them difficult to understand so
we are doing a rollback of them in the default ruleset in favor of the
syntax without exceptions.
