Give autogen bots on client.drmemory a separate clobber step

Give autogen bots on client.drmemory a separate clobber step

Some bots were converted to recipes using some script that automatically
rewrites the old buildbot config. These bots don't use the regular recipes
machinery, so they didn't get converted as part of the work in bug 574557.

Also remove all.sln; these bots have been building using ninja for a long time.

dpranke: review (this is 2/2 in this series)

I asked bruening if this waterfall is still needed or if we can delete it. He
said it's needed for a while longer while they're looking for alternatives.
