Subject: [PATCH 1/2] Revert "nixos/resolved: apply transformations to keys
 within resolved section"

This reverts commit 66353ca989dd68b3070f8932c048860e8354bc01.

In the meantime a new option was added that consumes the
`transformSettings` function, which broke by looking at just at the
Resolve section.

Subject: [PATCH 2/2] nixos/systemd-resolved: apply transformation to resolve
 section

In a previous change the transformSettings function was modified to look
at the Resolve section, but since it got a second consumer in the mean
time this regressed. We now target the resolved.conf explicitly instead.
