Bug#802344: qtlocation-opensource-src: Do not run tests when building arch:all packages

[Lisandro Damián Nicanor Pérez Meyer <lisandro@debian.org>]

Source: qtlocation-opensource-src
Version: 5.4.2-2+b1
Severity: normal

qtlocation's tests get run when building only arch-all packages and tests fail.
We shouldn't be running tests here.
