smcroute: make build id optional

The build id contains the build timestamp by default.
Make this field optional.
Build timestamp prevents reproducible builds [0].
Thanks to the debian project for the patch.

+Description: Make output of build id optional
+ With free software, anyone can inspect the source code for malicious flaws.
+ But the software is often provided as binary packages to its users. The idea
+ of “deterministic” or “reproducible” builds is to empower anyone to verify
+ that no flaws have been introduced during the build process by reproducing
+ byte-for-byte identical binary packages from a given source.  See also:
+ https://wiki.debian.org/ReproducibleBuilds
+ .
+ Prior to this change a timestamp generated at build time is included in the
+ output of 'smcroute -v'. As a result the binary is unreproducible.
+ .
+ With this change, users that still want 'smcroute -v' to include a build id
+ can run './configure --enable-build-id' to get the build id back (or even
+ specify a custom build id).
+Origin: upstream, https://github.com/troglobit/smcroute/commit/73f6f14907f709e40689216291621ad26cd22ecd
