Add Netty substitution that addresses Camel Quarkus issue

[geoand]

Addresses the issue in Camel Quarkus with GraalVM 19.3.1 (it only appears in that version) where the native image generation fails with:

To diagnose the issue, you can add the option --report-unsupported-elements-at-runtime. The unsupported element is then reported at run time when it is accessed the first time.

Both the root cause tracking and the substitution were provided by @dmlloyd (hence the author of the commit)

[lburgazzoli]

we'll retest the quarkus side once merged

[geoand]

I am also linking the GraalVM issue that was opened to make tracking down such issues easier the future: oracle/graal#2076

[gsmet]

@geoand you're my hero :).

I added a very small comment, otherwise let's merge that one ASAP.

[geoand]

@gsmet I committed your suggestion, thanks for spotting the mistake!

[geoand]

The PR needs to be rebased onto master because in the meantime a PR was merged changing the FT stuff

[geoand]

#6594 also tested this with GraalVM 19.3.1 (and so did I locally)

[geoand]

The CI failure is a flaky test that has nothing to do with this PR (and is being tracked by @sberyozkin). I'm gonna merge once the other tests complete
