gitlab-ci: Use -fno-sanitize=function in the clang-user job
With -fsanitize=undefined, which implies -fsanitize=function,
clang will add a "type signature" before functions.
It accesses funcptr-8 and funcptr-4 to do so.
The generated TCG prologue is directly on a page boundary,
so these accesses segfault.
