Bug#1052671: minetest FTBFS with nocheck build profile

[Tobias Frost]

Control: tags -1 pending

running the unit tests during build has side-effects,
it creates the files that are installed into mintest-data
(arch:all).

Those files are needed for autopkgtest.

If the arch:all package would be created with nocheck active,
this would break autopkgtest for all other builds, unless the
arch:all package is reuploaded.

IOW, nocheck cant be used for this package.

To workaround, and make the release team happy, I will run the
unittests, if nocheck is enabled, in the build stage and just
ignore errors, if there are any.
