bpo-39189: Uses the io.DEFAULT_BUFFER_SIZE variable instead of defining it again

[GreatBahram]

Hello there,

This Pull Request replaces the BUFSIZE variable with the existing one inside the io module.

Explanation:

I just removed the BUFSIZE global variable and replaced it with the io.DEFAULT_BUFFER_SIZE variable.

I couldn't find an open issue for this, but I do believe it does not need one, as it is a trivial issue!

I checked other branches, this problem affects below branches as well.

• Python 2.7 Lib.py file
• Python 3.5 Lib.py file
• Python 3.6 Lib.py file
• Python 3.7 Lib.py file
• Python 3.8 Lib.py file

@GreatBahram can you alter the title with [bpo-39199](https://bugs.python.org/issue39199): <message>

@bedevere-bot accidentally edited my original message, ignore that and check the original one from edit history.

Anything else?

@GreatBahram, thank you. The bot isn't finding that you signed the CLA; I think you need to add your Github user name to your bug tracker account in order for it to be able to match it. Thanks!

[GreatBahram]

Yeah, the objection you mentioned was the problem.

Thanks
