support/scripts/pkg-stats: use aiohttp for upstream URL checking

This commit reworks the code that checks if the upstream URL of each
package (specified by its Config.in file) using the aiohttp
module. This makes the implementation much more elegant, and avoids
the problematic multiprocessing Pool which is causing issues in some
situations.
