tests: don't log manifest-file in test-strip-cross.t
I'm confident that the file is there only to help produce a certain
manifest log; there is nothing special about the file's filelog
itself. (And there already is a `hg debugindex --manifest` call higher
up in the file that shows the crossed linkrevs.)
