Fetch source and destination addresses with bpf from tcp kprobes, similar to how it is done for openssl lib.
Chunk contains both source address and destination address.
FD is no longer used to obtain addresses.

* Add `ABI` enum and morph the function according to the detected ABI
* Pass `goid` offset to an eBPF map to retrieve it in eBPF context
* Add `vmlinux.h` and implement `get_goid_from_thread_local_storage`
* Fix BPF verifier errors
* Update the comments
* Add `go_abi_0.h` and implement `ABI0` specific reads for `arm64`

* Add a comment
* Add macros for x86 specific parts
* Update `x86.o`
* Fix the map key type
* Add `user_pt_regs`
* Update arm64 object file
* Fix the version detection logic
* Add `getGStructOffset` method
* Define `goid_offsets`, `goid_offsets_map` structs and pass the offsets correctly
* Fix the `net.TCPConn` and buffer addresses for `ABI0`
* Remove comment
* Fix the issues for arm64 build

* Revert "Fix the issues for arm64 build"
This reverts commit 48b041b1b6.
* Revert `user_pt_regs`
* Add `vmlinux` directory
* Fix the `build.sh` and `Dockerfile`

* Update arm64.o
* x86
* arm64
* Fix the cross-compilation issue from x86 to arm64
* Fix the same thing for x86
* Use `BPF_CORE_READ` macro instead of `bpf_ringbuf_reserve` to support kernel versions older than 5.8
Also;
Add legacy version of thread_struct: thread_struct___v46
Build an additional object file for the kernel versions older than or equal to 4.6 and load them accordingly.
Add github.com/moby/moby
* Make #define directives more definitive
* Select the x86 and arm64 versions of `vmlinux.h` using macros
