[FIX] core: fix majorless upgrade

When we compare majorless scripts we must ignore the Odoo version.
Otherwise a module upgrade without major Odoo upgrade would fail to run
local scripts majorless scripts. That's what happens for example when
users click the upgrade button of a module.

Example: upgrade from `11.0.1.0` to `11.0.2.0`, with a local `2.0` folder
for upgrades.
```
11.0.1.0 < 11.0.2.0 < 11.0.2.0 -> False (check before this patch)
     1.0 <      2.0 <=     2.0 -> True  (check with this patch)
```
While still: upgrade from `11.0.2.0` to `12.0.2.0`
```
11.0.2.0 < 12.0.2.0 < 12.0.2.0 -> False (before this patch)
     2.0 <      2.0 <=     2.0 -> False (with this patch)
```

closes odoo/odoo#119147
