smtp: fix EOB handling
SMTP automatically appends a \n.\n to an upload if there is not already
one at the end of the input. The implementation had a bug where this did
not happen, depending on read size and buffering.

Change test 900 to reproduce the failure. The bug only happened for mail
body input of known length, where EOS was known on the last chunk read.
Change test 900 to use an input file and make it large enough.

Fixes #18798
Closes #19193
