[mod] py: remove uvloop (#5220)

We get some good stuff without uvloop, 13MB~ less of dependencies, 3
minutes of build time for armv7 saved, and we are one step closer to NT
compatibility. Although it's true that theoretically the raw performance
have worsened on network side (we only used uvloop for that), the latest
cpython versions have been improving on asyncio performance.
