build: Remove eap-wsc and wscutil from eap_sources

With the previous commit, wscutil now depends on ie.h.  Unfortunately,
wired also includes eap-wsc and wscutil in the build, but not ie, which
results in a link-time failure.

Fix this by droppig eap-wsc and wscutil from wired.  There's no reason
that ethernet authentication would ever use the WiFi Protected Setup
authentication.
