[Bug 1957194] [NEW] resume from hibernation broken when resume image is autodetected another case

[cvl-skubriev]

Public bug reported:

My issue very similar to
https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1769297

I am assuming that the code at about line 162 in `/usr/share/initramfs-
tools/init` like that:

```
        resume=*)
                RESUME="${x#resume=}"
                case $RESUME in
                UUID=*)
                        RESUME="/dev/disk/by-uuid/${RESUME#UUID=}"
                esac
                ;;
``` 

Only works if user wants to set resume partition as `UUID=some` at file
like `/etc/initramfs-tools/conf.d/resume`. But in the case when
initramfs hook resume automatically save `UUID=some` in initrd
`conf/conf.d/zz-resume-auto` file it doesn't matter. Including for
operate `DEV=$(readlink -f "$resume")` correctly in
`/usr/share/initramfs-tools/scripts/local-premount/resume`

Therefore I decide to add similar code to `/usr/share/initramfs-
tools/scripts/local-premount/resume` to fix an issue with resuming.

See a patch in attachment.
