www/websh: attempt to debug test-failures on Poudriere

When the tests succeed, they'll continue to succeed quietly.  However,
when they fail -- as they've been doing during package-building for
FreeBSD-14 for a few months now -- the output will now contain more
information, which will, hopefully, allow me to fix them for good.

+The two cookiecontext-tests fail repeatedly on Poudriere, but I'm
+unable to reproduce the failures on my own FreeBSD-14 box. These
+changes will make the test-failures more verbose, which might give
+me the clue necessary to fix them properly.
