lttng: Move platform logic to dedicated inc file

Some platforms support kernel tracing, some support userspace tracing.
This change:

* Moves the knowledge/config to one place in an inc file
* Allows lttng-tools to build without lttng-modules
* Hence enables tools+ust for riscv64
* Has the packagegroup just depend on lttng-tools which will pull in
  ust/modules as needed
