What this PR does / why we need it:

This small patch allows to download compatible driver versions instead of the currently configured one.
This is how it works:

• you have falco 0.37.1 installed that ships with driver 7.0.0+driver
• you run falcoctl driver install --compatible
• it lists prefixes on our s3 bucket under the driver/ prefix (https://download.falco.org/driver/)
• loads all semver-like driver versions
• fetches the newest compatible one (where compatible in this context means same major version)
• this means that for Falco 0.37.1 it would download driver 7.2.0+driver.

Now, we cannot do the same for the compilation because we have only local sources for the driver installed Falco was shipped with, but that's not a big deal for now. We could have a post-submit job triggered whenever a new driver version is added (https://github.com/falcosecurity/test-infra/tree/master/driverkit/config) that push driver sources configured for Falco under eg: https://download.falco.org/driver/$version/src/.

Disabled by default for now.

Special notes for your reviewer:

Keeping it as wip until we decide what to do for compilation too.

Given falcosecurity/libs#1283, i'd wait to merge this one until we clear it up (ie: we don't want falcoctl to automatically choose a newer driver that does not work :/ ).

Don't know whether we'll want to ever ship this though.
I am open to rebase this one if there's willing to merge the feature!
