Fix for sometimes flashing and unable to mount rootfs

Clear out unused rootfs blocks on reboot.

The rootfs, appfs, drivers Wyze partitions have a total size of 8978432.
This is the most I can write with a stock u-boot bootloader.
However the mtd partition is 13828096 bytes and runs into the old config partition
This causes JFFS mount issues because when JFFS tries to mount it reads some of
the old stuff and corrupts things.

To fix this we will zero out the unused blocks. After they are zeroed
we will mount the jffs filesystem which will autocreate CLEANMARKER
blocks.

Using new version of ingenic_videocap

Update video_settings.json to include OSD

Fix custom makefile patch

Work around for an issue where the rootfs.tar.xz file is corrupt

On occasion the rootfs.tar.xz file will be corrupted. Not entirely
sure of the cause. In addition the uboot flash process *should*
clear out the jffs partition but it does not. Frequently there are
files left over. This surfaces as the error:

tar: invalid tar magic

To get around this delete files in the /jffsroot on init if we
encounter the issue. This seems to stir the bits around and a
subsequent flash seems to work.
