(face-set-after-frame-default): Simplify. Don't apply

frame-specific X resource settings.  Set faces using a list of
frame parameters explicitly passed to the calling
function (e.g. make-frame).
(x-create-frame-with-faces, tty-create-frame-with-faces): Supply
explicit frame parameter list to face-set-after-frame-default.
