Subject: inc/test-eom-align: Fix MMDF-mbox `B' size calculation.

inc/test-eom-align: Fix MMDF-mbox `B' size calculation.

Also, have the email body end in what appears to be the MMDF magic
string for the first few bytes;  otherwise, the test mbox is just a
boring single email compared to the `A', From_, version.  Fixes
8699f1cc.
