churn: split email aliases from the right

This splits churn email aliases from the right, to enable incorrectly-specified
addresses that include equal signs to be mapped to correct addresses.  This
will enable aliasing of bad addresses (typically typos) such as:

sername=myusername

that appear in the churn output through a churn alias such as:

sername=myusername = myusername

whereas previously splitting from the left would not enable this behavior.
