Subject: sys-cluster/spark-bin: conditionally install pre-compiled JARs.

Spark 2.4.x JARs comes in two flavours:
* Pre-compiled with Scala 2.11.
* Pre-compiled with Scala 2.12.

Add conditions to install either one of these flavours. Also do not
install Spark + Hadoop JARs anymore but only Spark JARs.

Package-Manager: Portage-3.0.9, Repoman-3.0.2
