Some images with ESP, e.g. the `rhel-ec2-aarch64`, have the `/boot` on
a separate partition. `image-info` currently produces traceback on such
images, e.g.:
Traceback (most recent call last):

with open(f"{tree}/grub2/grubenv") as f:
FileNotFoundError: [Errno 2] No such file or directory: '/tmp/tmp3i__6m1w/grub2/grubenv'
The reason is that `grub2/grubenv` on the `/boot` partition is a symlink
to `../efi/EFI/redhat/grubenv`. However the `efi` directory on the
`/boot` partition is empty and the ESP must be mounted to it for the
expected path to exist.
Modify `image-info` to mount the ESP to `efi` directory if it exists on
the inspected partition.
