libutils: relax noreturn label

Replaces attribute label identifier noreturn with __noreturn__ to
prevent conflicts when importing code which defines label noreturn
itself as a macro. This change applies suggestion from the GCC
documentation [1], applicable even prio GCC 4.x.x, cited below.

> You may optionally specify attribute names with ‘__’ preceding
> and following the name. This allows you to use them in header
> files without being concerned about a possible macro of the same
> name. For example, you may use the attribute name __noreturn__
> instead of noreturn.
