Scripts sometimes need the relative path from the current working directory to the repository's working tree root (cdup). While this information can be retrieved through `git rev-parse --show-cdup`, `git repo info` does not currently expose it as a scriptable key. Introduce the `path.cdup` key to `git repo info`. The key returns the path from the current working directory to the root of the working tree, returning the empty string when invoked from the working tree root.

What happens when the current working directory is outside the
working tree? For example:
$ GIT_WORK_TREE=/tmp/x; export GIT_WORK_TREE
$ GIT_DIR=$(pwd)/.git; export GIT_DIR
The current implementation yields an empty string:
$ git repo info path.cdup
path.cdup=
However, 'git rev-parse --show-cdup' produces:
$ git rev-parse --show-cdup
/var/tmp/x
Whether this discrepancy matters is unclear. However, if the goal
is to consolidate all repository path-related items under the
'git repo info' umbrella, this difference sticks out.
