    Add CI testing job on CentOS (!4)
    
    Add GitLab Continuous Integration job named 'test' which runs the
    GParted unit tests and distcheck.  Note that the job starts from a fresh
    official CentOS Docker image so also has to rebuild GParted too.
    
    So far this job fails on unit test test_BlockSpecial.  Fragment of the
    CI job log:
    
        make  check-TESTS
        make[2]: Entering directory `/builds/mfleetwo/gparted/tests'
        make[3]: Entering directory `/builds/mfleetwo/gparted/tests'
        PASS: test_dummy
        FAIL: test_BlockSpecial
        PASS: test_PasswordRAMStore
        PASS: test_PipeCapture
        make[4]: Entering directory `/builds/mfleetwo/gparted/tests'
        make[4]: Nothing to be done for `all'.
        make[4]: Leaving directory `/builds/mfleetwo/gparted/tests'
