Create vndkproduct.libraries.txt

Some VNDKs will be available to product modules by adding
'product_available' property. These VNDK libs will be listed in
vndkproduct.libraries.txt and tracked by the build system for the
changes. The product available VNDK list will be frozen by the
release process.
