Use virtual Java packages on Red Hat and set java_bin

This uses the virtual packages jre-VERSION-headless instead of
explicitly openjdk. This allows other JREs to provide the same.

It also uses an explicit path to the JRE specific java bin. At least on
EL9 this allows the following upgrade path to work:

    dnf install https://yum.puppet.com/puppet7-release-el-9.noarch.rpm
    dnf install puppetserver
    dnf install https://yum.puppet.com/puppet8-release-el-9.noarch.rpm
    dnf upgrade puppetserver

Prior to this patch it would break, because it used /usr/bin/java which
will point to Java 8. By using /usr/lib/jvm/jre-17/bin/java we know for
sure it is Java 17.
