    iproute2: stop writing unused snapshot information
    
    iproute2 already generates and uses a proper version string based off
    of git since 2020 [1]. Since the aforementioned commit has already
    removed the include for SNAPSHOT.h, this bit of code has had no effect
    since then other than disabling the built-in configure script invocation.
