cmNinjaTargetGenerator: fix DependInfo.json generation location

Commit aafd771529 (cmNinjaTargetGenerator: use `GetObjectFileDir` where
possible, 2025-05-21) from !10812 accidentally converted the
`GetTargetDependInfoPath` from an always-absolute path to a
relative-for-ninja path. This works fine as everything ended up doing
`ConvertToNinjaPath` as necessary *except* the code which actually wrote
the file. That needs an absolute path in order to generate it in the
correct location.

Fixes: #26983
