    gitlab-ci.yml: Add oss-fuzz build tests
    
    This tries to build and run the fuzzers with the same build-script used
    by oss-fuzz. This doesn't guarantee that the builds on oss-fuzz will
    also succeed, since oss-fuzz provides its own compiler and fuzzer vars,
    but it can catch changes that are not compatible with the the
    ./scripts/oss-fuzz/build.sh script.
    The strange way of finding fuzzer binaries stems from the method used by
    oss-fuzz:
