py3: fix string issues of email message in test-import.t

- payload can be bytes
- headers must be unicode on Python 3
- need to call msg.as_bytes() on Python 3, but msg.as_string() on Python 2,
  where bytes(msg) magic works

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
