bug#29426: guix: "make check" test "utmpx-entries" fails

[Adonay Felipe Nogueira]

Currently, "make check" test "utmpx-entries" fails, to reproduce, do:

--8<---------------cut here---------------start------------->8---
git clone "https://git.savannah.gnu.org/git/guix.git";
guix environment guix
./bootstrap
./configure --localstatedir="/var"
make check
--8<---------------cut here---------------end--------------->8---

The test fails in foreign system distribution (Trisquel 7, based on
Ubuntu 14.04).

Last attempt was based on commit
907ab9e8cbab10413848dfc8982cfc851e03903f.

The "test-suite.log" file is attached.
