Subject: [PATCH] busybox module: add BUSYBOX_LIST variable

When installing the Busybox module, Dracut attempts to execute busybox --list
to get a list of all installed busybox modules.

Executing a cross-compiled busybox won't work when the binary is a different
architecture from the host. To fix this issue, allow a user to specify a list
of Busybox files via the "BUSYBOX_LIST" variable and execute busybox --list
if the list is empty.
