tests: slightly modify a linkrev test to prepare for expanding it
The test case checks that the copy tracing code doesn't get confused
by linkrevs when walking a file's ancestors. This patch chnages the
test slightly so a second commit is grafted, thus producing a second
"bad" linkrev. I'll use this in the next patch to demonstrate a bug.
