/usr/bin/grub2-editenv is indeed not in the inst-sys. It's also not a usr-merge problem (see bug #1204528). It is part of package grub2: % rpm -qf /usr/bin/grub2-editenv grub2-2.06-150400.11.17.1.x86_64 but it's 1.5 MB large, so it might intentionally be removed from the inst-sys to minimize its size.
