Test 079 fails in the arm64, s390x and ppc64le LXD containers on Travis
(which we will hopefully enable in our CI soon). These containers
apparently do not allow large files to be created. Test 079 tries to
create a 4G sparse file, which is apparently already too big for these
containers, so check first whether we can really create such files before
executing the test.

For the record: It's working on s390x as noticed by Cleber. It's only
failing on arm64 and ppc64le. After fixing the problem with 060 which
fails on all three architectures, I did not pay enough attention when I
wrote this commit message here and thought that this would be the very
same problem, but apparently it is working on s390x. Thus "s390x" should
be removed from the commit message.
