system: change label for BR2_INIT_NONE
Currently, the label reads "None", but it can be a bit misleading.
Indeed, since its inception in 0c00636e8bbc (system/init: add option for
no init system), what it really meant was "none of the above", as
briefly laid out in the commit log for 0c00636e8bbc (typo included):
Can be usefull if a local package provides an init procedure.
This was later refined in 4d185e5ec51b (system: add help entry to "none"
init system), which explained:
Add a comment that states the user has to provide his own init
system, either via a package or a rootfs overlay.
So, change the label to better reflect that.
