[Linux interceptor] Fix sanitizer component builds

In a component build, our getaddrinfo override appears in a shared
object, but the sanitizer's interceptor appears in the main executable.
So getaddrinfo() always called the interceptor, and the interceptor
called our override. So our override should not call the interceptor.
