net/sysconfig: fix available check on SUSE distros

In addition to ifup/ifdown the sysconfig renderer looks for
evidence that the sysconfig directory is properly populated.
This secondary check only considered RedHat specific location.
Fix this by adding a SUSE specific file and returning True if
either RedHat or SUSE file is present.

LP: #1849378
