ash: allow shell scripts to be embedded in the binary
...
To assist in the deployment of shell scripts it may be convenient
to embed them in the BusyBox binary.
'Embed scripts in the binary' takes any files in the directory
'embed', concatenates them with null separators, compresses them
and embeds them in the binary.
When scripts are embedded in the binary, scripts can be run as
'busybox SCRIPT [ARGS]' or by usual (sym)link mechanism.
embed/nologin is provided as an example.
