This is so that the ‘replacement’ field of ‘calcmysky’, when there is
one, inherits the same transformations in ‘calcmysky-qt5’.  Quoth the
‘package/inherit’ docstring:

  Like (package (inherit P) OVERRIDES ...), except that the same
  transformation is done to the package P's replacement, if any.  P must
  be a bare identifier, and will be bound to either P or its replacement
  when evaluating OVERRIDES.
