bug#22612: guix make check failure for syscalls: "FAIL network-interfaces returns one or more interfaces"

[Danny Milosavljevic]

Package: guix
Version: git from an hour ago

When I bootstrap guix using
  git clone, `guix environment guix`, ./bootstrap && ./configure 
--localstatedir=/var && make check
starting from GuixSD, then I get at the make check:

...
FAIL: tests/syscalls.scm
...
# TOTAL: 59
# PASS:  58
# SKIP:  0
# XFAIL: 0
# FAIL:  1
# XPASS: 0
# ERROR: 0

File "tests/syscalls.log" contains:
