main: Initialize event loop before command_line_scan

The call to `event_init()` was too late. `command_line_scan()` in `main()` could
already need the loop initialized. Ref https://github.com/neovim/neovim/issues/3045#issuecomment-123405833.

A consequence of this change is that it was necessary to move the
`channel_from_stdio()` call to `command_line_scan()` when embedded_mode is set.
