Subject: Reporting a bug loads many Gnus libraries

Current trunk on GNU/Linux:

emacs -Q
M-x report-emacs-bug

Typing C-c C-c to send the bug loads 22 extra libraries, including
several Gnus ones:

    gnus-msg gnus-art mm-uu mml2015 epg-config mm-view smime dig gnus-sum
    nnoo gnus-group gnus-undo nnmail mail-source format-spec gnus-start
    gnus-spec gnus-int gnus-range gnus-win gnus gnus-ems

This extra complexity leads to unexpected bugs like #5299.

In contrast, with mail-user-agent = sendmail-user-agent, sending a
report loads exactly 1 extra library (mail-utils).

After sending a bug report with message-user-agent, there are 146
libraries loaded. With sendmail-user-agent, the number is 93.
