bug#6967: flymake not cleaning after itself (kill-buffer)

IIUC Semantic visits those files "temporarily" (i.e. it will kill the
buffer afterwards, although probably not if the buffer already existed).

I think this need is not specific to Semantic, and so we should provide
this functionality in files.el.  Maybe in a `with-found-file' macro.
