[Reproducible-builds] Bug#833380: roaraudio: please make the build reproducible

Source: roaraudio
Version: 1.0~beta11-7

Hi,

Whilst working on the "reproducible builds" effort [0], we noticed
that roaraudio could not be built reproducibly.

It also affects anything that uses libroar-dev, eg. roarplaylistd.

Patch attached.
