[PATCH libSM] doc: clean the grohtml png files so distcheck succeeds

[Alan Coopersmith]

Strange - I don't see any *png files in my output, just the html.
(My system has groff 1.19.2.)

If they're being made for others though (different versions or
dependencies installed I'd guess), then makes sense to clean them.
