Kernel config extraction in S24

[m-1-k-3]

• What kind of change does this PR introduce? (Bug fix, feature, docs update, ...)

Feature
Small bug fixes

• What is the current behavior? (You can also link to an open issue here)

No extraction (and no testing) of kernel config from binary kernel

• What is the new behavior (if this is a feature change)? If possible add a screenshot.

Extract kernel config from binary kernel with https://raw.githubusercontent.com/torvalds/linux/master/scripts/extract-ikconfig (which is integrated in s24 module)

• Limitations:

Kernel config checks with EMBA parameter -k is currently disabled and needs some further attention!

Testfirmware: https://github.com/OWASP/IoTGoat/releases/download/v1.0/IoTGoat-raspberry-pi2.img
Start EMBA the following way: sudo ./emba.sh -f ~/Downloads/IoTGoat-raspberry-pi2.img -l ~/emba_logs_IoTGoat -S -p ./scan-profiles/default-scan.emba -m s24

Tested with openwrt image

guessing this is expected/normal behavior

This is an error from vmlinux_to_elf. Happens on different firmware files. This error does not affect the rest of the process.

Probably we should dump the errors to /dev/null
