[llvm-cov] Fix a use-after-free
Taking a lock before appending to a vector does no good unless threads
reading from the vector also take the lock, because the vector could be
re-sized.
I don't have a good isolated test for this. I found the issue with ASan
while testing a large project. I'm working on a bot that does this.
