bcm53xx: use iflag=skip_bytes for dd command during sysupgrade
Since BusyBox 1.25.0 dd command supports iflag=skip_bytes which allows skipping requested amount of bytes without reducing blocksize. Thanks to this we can leave default blocksize and let dd work more efficiently. On Netgear R6250 "dd skip=58 iflag=skip_bytes" can be 5 times faster than "dd bs=58 skip=1" when extracting TRX out of CHK. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
