Updating package maker to create packages safely

[vanridal]

• package_maker would not create .building prefix when build payload
• changed to use pre_variant_install from repository to get build_prefix
• Variant is installed now after make_base and make_root calls
• using get_package_payload_path to generate base path
• Note: the variant passed to make_base and make_root is now a memory repo variant
