Fix missing dependencies for RPM/DEB packages

[tlrx]

Since elasticsearch doesn't shade artifacts anymore (see #11522), the dependencies list for RPM/DEB must be updated. In this commit, we package all maven libs by default except the generated -shaded/-tests/-test-cours JARs and slf4j-api (marked as optionnal).

I did not try to run it but it looks good to me.

That said, I had a discussion with @rmuir about how we should declare what we want to embed in plugins. The conclusion was that we should somehow declare explicitly what we want to add instead of excluding... See discussion here: #11647 (comment)

So may be we should be consistent here with that position. WDYT?

@dadoonet thanks! I think this case is different from plugins. The deb/rpm is just another way to package elasticsearch: there's no additional code or dependencies needed and there won't be any conflicting lib like in plugins. Here we need to be sure to include everything, so excluding only what we don't need makes sense to me.

@tlrx LGTM

@dadoonet agreeing with @tlrx here, I think we can keep the behaviour. We already broke deb/rpm packaging once, by not including ant-lr in rpm/deb and thus having lucene expressions not working.

thanks @spinscale !
