Cannot detect openSUSE 15.3

[pawel-kedzior-sw]

The library fails to properly recognize openSUSE 15.3

osutil.GetDisplay()
expected: openSUSE
actual: Linux

distro := osutil.GetDist()

expected: distro.Display to be openSUSE
actual: distro.Display is empty

expected: distro.Codename to be Leap
actual: distro.Codename is empty

Notes:
distro.Release is correct, 15.3

lsb_release - command is not available

cat /etc/os-release returns
