Bug#894493: lexicon: please make the build reproducible

[Chris Lamb]

Source: lexicon
Version: 2.2.1-1
Severity: wishlist

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that lexicon could not be built reproducibly as it includes non-
determinstic output in its PKG-INFO file due to iterating over
the filesystem and using that sorting to generate the "Keywords"
variable.

Patch attached.
