[PATCH nft v4 05/17] tests/shell: normalize boolean configuration in environment variables

[Thomas Haller <thaller@redhat.com>]

Previously, we would honor "y" as opt-in, and all other values meant
false.

- accept alternatives to "y", like "1" or "true".

- normalize the value, to either be "y" or "n".
