busybox: Add support for busybox-init
in config metadata we can configure busybox based init and device
initializer ( mdev ) using e.g.
VIRTUAL-RUNTIME_dev_manager = "busybox-mdev"
VIRTUAL-RUNTIME_login_manager = "busybox"
VIRTUAL-RUNTIME_init_manager = "busybox"
VIRTUAL-RUNTIME_initscripts = "initscripts"
VIRTUAL-RUNTIME_keymaps = "keymaps"
DISTRO_FEATURES_BACKFILL_CONSIDERED += "sysvinit"
busybox can be used to provide init system
combined with mdev it makes it a complete init
system for really tiny systems.
This patch uses above defines to configure features in busybox to enable
the init system and mdev in a configurable manner
