Remove ccov-preprocessing target

The only purpose of the job was to create the 'ccov' directory in the
binary directory to store all the generated code coverage files.

Rather than generating the directory at build time using a target,t he
directory is now created at CMake generation time, meaning the build-
time target is no longer necessary.
