repack/pack-objects: mark --full-name-hash as experimental

This option is still under discussion on the Git mailing list.

We still would like to have some real-world data, and the best way to
get it is to get a Git for Windows release into users' hands so that
they can test it.

Nevertheless, without the official blessing of the Git maintainer, this
optionis experimental, and we need to be clear about that.
