builtin/send-pack: stop using the_repository

Remove the_repository global variable in favor of the repository
argument that gets passed in "builtin/send-pack.c".

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