Vedant Kumar 4a54abeacd [llvm-cov] Do not allow ".." to escape the coverage sub-directory ...

In -output-dir mode, file reports are placed into a "coverage"
directory. If filenames in the coverage mapping contain "..", they might
escape out of this directory.

Fix the problem by removing ".." from source filenames (expand the path
component).
