What type of PR is this?

Uncomment one (or more) /kind <> lines:

/kind bug

/kind rule-update

Any specific area of the project related to this PR?

/area rules

What this PR does / why we need it:

GKE regularly calls /exec.fifo from both a system level, and within
individual falco pods. As is this triggers errors multiple times every
hour. This change adds /exec.fifo to the expected files below root that
will be called.

Which issue(s) this PR fixes:

Fixes #738

Special notes for your reviewer:

The rule update will need to be propagated to the helm chart on https://github.com/helm/charts/tree/master/stable/falco as well before the issue is resolved. I've cloned the helm/charts repo and have updated mine locally in the meantime to test and it has resolved the error for me.

Does this PR introduce a user-facing change?:

Adds /exec.fifo to known_root_files (GKE)

Thanks for sending this PR @jonnymcgow7 !

Would you please rebase it? :) - Nevermind, done by myself

The Helm chart will be promptly updated with the next release (cc @nestorsalceda).
