[Reproducible-builds] Bug#810509: apt: please make the build reproducible (randomness)

Hi!

While working on the “reproducible builds” effort [1], we have noticed
that apt could not be built reproducibly.

The attached patch removes extra randomness from the build system,
ensuring a stable file order when linking the built object.
This particular issues is currently visible only on our armhf builds due
to a limit in our infrastructure, but can be tested by performing the
builds using the fuse fs disorderfs.

Once applied, apt can be built reproducibly in our current experimental
framework.
