clone: forbid --bare --separate-git-dir <dir>

Browse source 
The --separate-git-dir option was introduced to make it simple to put
the git directory somewhere outside the worktree, for example when
cloning a repository for use as a submodule.

It was not intended for use when creating a bare repository. In that
case there is no worktree and it is more natural to directly clone the
repository and create a .git file as separate steps:

        git clone --bare /path/to/repo.git bar.git
        printf 'gitdir: bar.git\n' >foo.git

Forbid the combination, making the command easier to explain.
