Turn into virtual package for update to 19.3.0

With the 19.3.0 release, GraalVM supports two Java versions: Java 8 and
Java 11. This also affects all sibling packages, including FastR, so the
former fastr-bin package is split in two: fastr-jdk8-bin and
fastr-jdk11-bin. To leave old installs functional when they update, this
package is retained, but only as a “virtual” package with no contents
except for its dependencies.

Since this package only used to provide the Java 8 version, it now
declares a dependency on fastr-jdk8-bin (users may additionally or
instead install fastr-jdk11-bin, if they want to). Users should install
the real package explicitly; I intend to remove this one eventually.
