Bug#1010845: logapp: please make the build reproducible

[Chris Lamb]

Source: logapp
Version: 0.16-1
Severity: wishlist
Tags: patch

Hi,

Whilst working on the Reproducible Builds effort [0] we noticed that
logapp could not be built reproducibly.

This is because the md5sums file is "manually" generated, and its
contents were sorted based on the underlying filesystem ordering.

Patch attached.
