ifcfg-rh: preserve existence of wired setting

Currently the plugin doesn't preserve the existence of a wired setting
because the writer saves only variables with non-default values and,
especially, the reader always creates the setting.

Fix this; now the writer writes HWADDR even if empty when the setting
is present; the reader creates the setting when at least one property
is found.
