v7.8.0 is not reproducible

[mohammadrafigh]

I followed the build process but received 2 different hashes from the binary in repo and what I built:

github: b0fc047c7789bee9fba72e5720fb5c8129c9a32f94f7fe9dca4f4675c8d3ddc2
built binary: aa5d303ae15d2b5dd3ace06ad4d8665c644efbfba1946c25aa5e25d6d17ed917

to see the differences, I transformed binaries to hex formatted files:

$ xxd bin/firmware.keepkey.bin > built-bin.hex
$ xxd firmware.keepkey.bin > github-bin.hex

then got a diff excluding signature part:
