Subject: Alternative to Autobuild-based use_prebuilt_binary

It still parses autobuild.xml, but using `xmllint --xpath`.
It searches for the "common" version of the package first, if not
found then it searches for the platform specific version.
The URL parsed is then fed to cURL, determining our own output
file name (since I couldn't find a way to extract remote file name
easily using cURL) assuming the ones we need all have tar.zst
extension now. It downloads to /tmp and finally extracts to packages.
