src/meta-openembedded:sassc: ignore CVE-2022-43357

This CVE is fixed in current libsass recipe version.
So wrapper around it will also not show this problem.
It's usual usecase is to be statically linked with libsass which is
probably the reason why this is listed as vulnerable component.

[1] links [2] as issue tracker which points to [3] as fix.
[4] as base repository for the recipe is not involved and files from [3]
    are not present in this repository.
