bitbake: bitbake: Drop older python version compatibility code

cooker: We can call multiprocessing close() unconditionally and tweak a
comment give 3.8 is now the minimum version.

lib/bb: We can drop the logger addition code only needed before 3.6

asyncrpc/hashserv: Since the minimum version is 3.8, we can drop the
conditional code.
