busybox: separate inittab into own package, due to SERIAL_CONSOLES being machine-specific

* Create busybox-inittab recipe to produce machine-specific package with /etc/inittab
  and necessary getty calls for a machine, based on SERIAL_CONSOLES, similar to how
  sysvinit-inittab was done

* Since CONFIG_FEATURE_USE_INITTAB is controlled by VIRTUAL-RUNTIME_init_manager, make
  main busybox package RDEPENDS on busybox-inittab when init_manager is set to busybox
