firmware-utils: mkmylofw broken since 9. Apr 2021

[Sven Roederer]

Hi,

since some days my master builds failing for ath79-generic. I was able to 
narrow it to running "mkmylofw for compex_wpj344-16m".
The tool runs till the drive is full, currently my "compex_wpj344-16m-
squashfs-cpximg-6a08.bin.new" is 161GB and growing ...

Has anyone else seen this?
I'll check to see which of the relevant 6 commit trigger this during the next 
days.

Full command is:

freifunk-berlin/openwrt/build_dir/target-mips_24kc_musl/linux-ath79_generic/

% pad)) % pad" newsize='size + pad' ; [ $newsize -lt $((0x660000)) ] &&
