`baseimage-root: Missing ostree -> sysroot/ostree link` for images without documentation

[champtar]

Buidling a base image with rpm-ostree with documentation: false

baseimage-root fails when running on usr/share/doc/bootc/baseimage/base

bootc/lib/src/lints.rs

Lines 624 to 630 in 5abda6a

	// If we have our own documentation with the expected root contents
	// embedded, then check that too! Mostly just because recursion is fun.
	if let Some(dir) = dir.open_dir_optional(BASEIMAGE_REF)? {
	if let Err(e) = check_baseimage_root_norecurse(&dir, config)? {
	return Ok(Err(e));
	}
	}

bootc rpm only has files marked as documentation

# rpm -qd bootc
/usr/share/doc/bootc/README.md
/usr/share/doc/bootc/baseimage/base/ostree
/usr/share/doc/bootc/baseimage/base/usr/lib/ostree/prepare-root.conf
/usr/share/doc/bootc/baseimage/dracut/usr/lib/dracut.conf.d/10-bootc-base.conf
/usr/share/doc/bootc/baseimage/systemd/usr/lib/kernel/install.conf
...

So the folders are still presents in the image, not the files

This can be fixed by not marking the %dir under /usr/share/doc/bootc in the specfile so they don't appear in rpm -q --dump bootc
