Andrew Chow 405b86a92a Replace lcov -r commands with faster way
Instead of using lcov -r (which is extremely slow), first use a python script to perform bulk cleanup of the /usr/include/* coverage. Then use lcov -a to remove the duplicate entries. This has the same effect of lcov -r but runs significantly faster
