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 TruffleRuby,
so the former truffleruby-bin package is split in two: truffleruby-jdk8-bin and
truffleruby-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 declares
a dependency on truffleruby-jdk8-bin now (users may, if they want to,
install truffleruby-jdk11-bin additionally or instead). Users should
explicitly install the real package; I will remove this one eventually.
