MODULES-8698: Fix $install_path on CentOS with tar.gz package type

[fraenki]

https://tickets.puppetlabs.com/browse/MODULES-8698

When using tar.gz packages on CentOS, the architecture is not part of the name of the installation directory. In this case it's just "jdk1.8.0_201" instead of "jdk1.8.0_201-amd64".

This fix is required to avoid running Exec on every Puppet run when using the following configuration:

java::oracle { 'jdk8':
  basedir => '/mnt'
  java_se => 'jdk'
  version_major => '8u201'
  version_minor => 'b09'
  url_hash => '42970487e3af4f5aa5bca3f542482c60'
  package_type => 'tar.gz'
}

Info: Applying configuration version '1551106786'
Notice: /Stage[main]/Java::Oracle[jdk8]/Exec[Install Oracle java_se jdk 8 8u201 b09]/returns: executed successfully
Notice: Applied catalog in 2.99 seconds
