Chroot for depmod and modinfo

modinfo cannot always work with output from newer or different depmod.

Specifically, this fixes the case where modinfo sch_fq_codel fails with
"module not found" on CentOS Stream 9 images built from Fedora 40. When
depmod from Fedora 40 is used, modinfo in the image fails with "module
not found". When depmod from inside the image is used, modinfo succeeds
as expected.

We'd rather not do this but in this case there's no other option.
