For some reason (not obvious to me from reading the spec file), and I'm pretty sure it's not intentional, grub2-ppc64le ships an empty /boot/loader/entries directory. This is not something owned by grub, and especially not owned by just ppc64le.

This caused an install failure just on this architecture with bootc/ostree.

[root@2a0a2e13ab18 /]# rpm -q grub2-ppc64le
grub2-ppc64le-2.12-5.el10.ppc64le
[root@2a0a2e13ab18 /]# 
[root@2a0a2e13ab18 /]# rpm -qlv grub2-ppc64le|grep loader
drwx------    2 root     root                        0 Jan  8 19:00 /boot/loader/entries

I started cleaning this up automatically in https://github.com/coreos/rpm-ostree/pull/5279 but let's just delete this from the package too.
