The list of supported filesytems goes dynamic.
- The plain list of "should be a supported filesystem" finally is fixed,
now it scans /proc to see if the kernel is able to mount it, if not it
modprobes it and as a failover tries to insmod it from the real rootfs
/lib/modules directory if it can.
- This should fix - en passant - the "drop to busybox shell if a ntfs
filesystem is found while scanning for persistence media" bug as well.
