    Create initial GitLab CI job which builds on CentOS (!4)
    
    Initial GitLab Continuous Integration configuration with a single job
    named 'build' which just confirms GParted can be built and installed on
    the latest official CentOS Docker image.
    
    Closes !4 - Add GitLab CI jobs to build and test GParted
