From: ZheNing Hu <adlternative@xxxxxxxxx>
`git ls-files --stage` default output format is:
[<tag> ]<mode> <object> <stage> <file>
sometime we want to find a path's corresponding objectname,
we will parse the output and extract objectname from it
again and again.
So introduce a new option `--only-object-name` which can only
output objectname when giving `--stage` or `--resolve-undo`.

ls-files.c: add --only-object-name option
Something we want to extract objectname from git ls-files --stage, but
git ls-file don't support something like --format=%(objectname) (which
git ls-tree have implemented)
So now add a new option --only-object-name which can only output
objectname.
(Maybe we should add something like git ls-files --format ?)
