While there is not real bug in this case, using re.ASCII is safe when re.IGNORECASE is used. This commit removes dead copy in email.util too.

This was probably left in place for backward compatibility reasons (just in case someone was using it). Or it may have been overlooked. No way to tell :) But, probably better to not delete it if you backport this change.

Since this change doesn't actual bugfix (B and Q don't have another lower cases),
I won't backport it to Python 3.6.
