Add the email-style subject prefix (e.g. "Subject: [PATCH] ") directly
when it's needed instead of letting log_write_email_headers() prepare
it in a static buffer in advance. This simplifies storage ownership and
code flow.

This slows down the last three tests in p4000 by ca. 3% for some reason,
so we may want to only do the first part for now, which is performance
neutral on my machine.
