.gitlab-ci.d/buildtest.yml: Use -fno-sanitize=function in the clang-system job

The latest version of Clang (version 18 from Fedora 40) now reports
bad function pointer casts as undefined behavior. Unfortunately, we are
still doing this in quite a lot of places in the QEMU code and some of
them are not easy to fix. So for the time being, temporarily switch this
off in the failing clang-system job until all spots in the QEMU sources
have been tackled.
