im_color_ramp: write to the Attribute parm, drop the unused im_remap1

The output Attribute parm was never read: all four wrangles hardcoded
v@Cd. They now write the ramp colour through setpointattrib or
setprimattrib with the parm's name, so the default still gives Cd.
The chramp result is bound to a vector first because chramp is
overloaded and the bare call made the set*attrib call ambiguous.
im_remap1 had no inputs, outputs or references, so it is gone.
