Linux Kernel extraction, ELF output

[Caesurus]

If a linux kernel is extracted, attempt to output usable ELF format that is easily importable in Binary Ninja/IDA/Ghidra. Uses https://github.com/marin-m/vmlinux-to-elf to accomplish this. Original extracted file is maintained alongside the .elf file.

In anticipation of questions:

• Q: if the extracted output is already a ELF file, why try to rebuild it anyway?
• A: the extracted file could be a stripped ELF, in which case it's still useful to rebuild and recover symbols from symbol table.
