builtin/maintenance: fix loose objects task emitting pack hash

The "loose-objects" maintenance tasks executes git-pack-objects(1) to pack all loose objects into a new packfile. This command ends up printing the hash of the packfile to stdout though, which clutters the output of `git maintenance run`. Fix this issue by disabling stdout of the child process.
