Pass original spec just after creating the face-widget

* lisp/cus-edit.el (custom-face-get-current-spec-unfiltered):
New function, extracted from custom-face-get-current-spec.
(custom-face-get-current-spec): Use it.
(custom-face-state-set): Take an optional argument, to decide
if we should check against a filtered or unfiltered spec.
(custom-face-value-create): Use the new optional argument.
