bitbake: bitbake-worker/cooker: Increase default pipe size

The default pipe size is 64kb on builds, which can be inefficient
for larger log files from workers. Increase the pipe size to 512kb
since build systems have decent amounts of memory and this is a more
efficient way of batching the data.

Tweak the default read sizes to match the pipe size for efficiency.

Since the contstant is only present in python 3.10 onwards, add
some compatibility code.
