Cleanup - test ELFs

[Lichtso]

• SBPF v2 ELF relocation tests must be removed as relocation itself will be removed
• SBPF v2 ELF static syscall execution tests must be removed because unresolved syscalls will become a verification error
• Marks and recompiles all other test ELFs as SBPF v1

New SBPF v2 ELFs will be added back in the upcoming changes to the call opcodes and strict ELF loader.
