Fix T62601: parenting to curve (follow path) causes offset 

Similar to T60623 / rB2894e75121d7.
Issue (when parenting with 'Follow Curve') is that the curves
CU_FOLLOW flag is set on the original, but not the
evaluated curve (yet), leading to misbehaviour in 'ob_parcurve()'.
Setting this on both now.
