Subject: [PATCH] travis: Add code coverage on success

Update the code coverage of the project on codecov for easy viewing.

Also the gcov on travis uses a different version which cannot
find the directory of the given files, and it needs to be specified
in the -o flag. Hence now we loop over the list of files and
run them independently.
