Bug#920411: mongo-c-driver: please make the build reproducible

Source: mongo-c-driver
Version: 1.13.0-1

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that mongo-c-driver could not be built reproducibly.

This/was partly due to the shipped mongoc-config.h file containing
the CFLAGS that were used to build the package, thus including the
buildpath in the calls to -f{debug,file}-prefix-map.

Patch attached, but if this file is not needed in the binary
packages, I would simply remove it.

(I think it also embeds the aforementioned CFLAGS into the resulting
libbson*.so too?)
