Add ARM64 support to eBPF (#1151)

* Define and use `BPF_CFLAGS` environment variable

* Add eBPF dependencies to `builder-from-amd64-to-arm64v8` and `builder-native-base`

* Add eBPF dependencies to `builder-from-arm64v8-to-amd64`

* Only compile x86 arch of Capstone for x86 target

* Build and install `libbpf` from source

* Fix `builder-from-arm64v8-to-amd64`

* Add `BPF_TARGET` environment variable

* Fix the eBPF verifier error on ARM64

* Fix `go_crypto_tls_ex_uprobe`

* Fix the check

* #run_acceptance_tests

* Fix the build script

* Include ARM64 files

* Bring back `x86.o`

* Generate both endianness

* Fix Dockerfile

* #run_acceptance_tests

* Determine the endianness on runtime if it's possible in Go (default little-endian) #run_acceptance_tests

* Revert "Determine the endianness on runtime if it's possible in Go (default little-endian) #run_acceptance_tests"

This reverts commit a2c83c6040.

* Remove big-endian files #run_acceptance_tests

* Fix Dockerfile #run_acceptance_tests
