builtin/for-each-ref: stop using `the_repository`

Remove the_repository global variable in favor of the repository
argument that gets passed in "builtin/for-each-ref.c".

When `-h` is passed to the command outside a Git repository, the
`run_builtin()` will call the `cmd_for_each_ref()` function with `repo`
set to NULL and then early in the function, `parse_options()` call will
give the options help and exit.
