Instead of using a falco_rule struct on the stack, use a single value
inside the falco_source struct. It's mutable as find_source returns a
const struct.
At very high event volumes (> 1M syscalls/second), even the tiny time
it takes to create/destroy the struct starts to add up, and this
switch has some small cpu savings.

This also fixes a couple of bugs. With the current implementation, the multi-ruleset feature is broken with multiple sources.
