Merge bitcoin#26473: test: Avoid collision with valid path names in getarg_tests/logargs

c8f9147 test: Avoid collision with valid path names in `getarg_tests/logargs` (Hennadii Stepanov)

Pull request description:

  This PR prevents test failure when "private" is a part of a valid path.

  For example, `/private/var` is a valid path on macOS for temporary files, which in turn causes test failure on CI for tests managed by the [CTest](bitcoin#25797) framework.
