The redundant character '0x0a' after the 192 bytes '0x00' padding broke
the factory image. We need to remove it to make things work again.
Fixes: e6769d11f3 scripts: fix missing character '0' issue in linksys image

# Write Linksys signature for factory image

# This is appended to the factory image and is tested by the Linksys Upgrader - as observed in civic.

# The footer is 256 bytes. The format is:
|
|
# .LINKSYS. This is detected by the Linksys upgrader before continuing with upgrade. (9 bytes)
|
|
# <VERSION> The version number of upgrade. Not checked so use arbitrary value (8 bytes)
|
|
# <TYPE> Model of target device, padded (0x20) to (15 bytes)
|
|
# <CRC> CRC checksum of the image to flash (8 byte)
|
|
# <padding> Padding ('0' + 0x20 *7) (8 bytes)
