Philip Withnall e960529532 ci: Exclude copylibs and fuzz tests from code coverage
The fuzz tests are run on a separate CI system, and we don’t care what
their code coverage is. The only reason they’re run on our CI systems at
all is as a smokecheck. They are not unit tests that we want to check
are running every line.

Similarly, exclude copylibs/subprojects as GLib is not responsible for
testing them. They have (or should have) their own unit tests and code
coverage metrics in their upstreams.
