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.
