Starting on coreos#449 `openat` is pretty dead upstream, and especially going forward as we start to do more nontrivial file things, it's really useful to have cap-std's additional verification that we aren't accidentally escaping the root. Signed-off-by: Colin Walters <walters@verbum.org>

CI error: error: boot data installation failed: Installing static GRUB configs: Copying static EFI: a path led outside of the filesystem
To copy /usr/lib/bootupd/grub2-static/grub-static-efi.cfg to boot/efi/EFI/fedora/grub.cfg, refer to doc, grub-static-efi.cfg should be relative to self, might use target_root instead of efidir, but not sure if it works as CONFIGDIR is not relative path.
