What type of PR is this?

/kind feature

Any specific area of the project related to this PR?

/area build

What this PR does / why we need it:

This PR introduces a Falco image based on RedHat's UBI (Universal Base Image). The UBI has a short release cycle with a special focus on security and stability. It has a smaller trusted computing base and a narrower exploit window than most publicly-available docker images. This is particularly helpful in hardened deployments with strict vulnerability scanning policies for agent admission.

Which issue(s) this PR fixes:

NONE

Special notes for your reviewer:

Example automation with a GHA workflow is available in the forked git repository.

Does this PR introduce a user-facing change?:

new(image): add Falco image based on RedHat UBI

As I mentioned in community call, I really like this! To add on top of what @araujof already mentioned, the image itself is also lighter than the large official one. So this means faster and easier security maintenance and lighter system footprint, sign me up :D !
The only drawback is that there are systems (especially old ones) where you can't use this image to compile the kmod or ebpf probe, in those cases you'll need to use the big one. However, the version of gcc that ships with UBI is compatible with most widely used kernels 👍 .

@LucaGuerra I fixed the package cache cleanup issue and set the default value you suggested for the UBI_VERSION. Thanks for your comments!
