[PATCH] test: Fix HTML rendering test

[Austin Clements <amdragon@MIT.EDU>]

The test designed to exercise Emacs' rendering of HTML emails
containing images inadvertently assumed w3m was available under Emacs
23.  The real point of this test was to exercise Emacs 24's shr
renderer, so if shr isn't available, we now fall back to html2text,
which comes with Emacs.
