Additions/linux/installer: correctly detect the Oracle Linux RPMs. bugref:3809: Linux installer maintenance Since the Oracle Linux RPMs use the normal Additions installer as a basis, the installer failed to detect them as a different type of installation. Fortunately they removed the uninstall script, causing this installer to fail early. This change adds script to detect them via the missing uninstall script.
