Attempt to fix Couldn't get ...validatedByFreeProfile EA

com.apple.installd.validatedByFreeProfile validation is really weird. This bypass worked as value size was smaller than expected, but is zero. I don't know if this is the cause of `Couldn't get ... EA` when sideloading for some users. Hope this fixes the issue
