Subject: firmware-utils: add support for TL-WR1043ND v4 to mktplinkfw

The TL-WR1043ND v4 uses a kernel image with a mktplinkfw header inside the
os-image partition of a tplink-safeloader image.

Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>

Backport of LEDE 51740990cd1d5375a566454e692b479986cba958
