[PATCH bpf-next 0/4] Add support for aarch64 to selftests/bpf/vmtest.sh

[Manu Bretelle <chantr4@xxxxxxxxx>]

This patchset adds initial support for running BPF's vmtest on aarch64
architecture.
It includes a `config.aarch64` heavily based on `config.s390x`
Makes vmtest.sh handle aarch64 and set QEMU variables to values that
works on that arch.
Finally, it provides a DENYLIST.aarch64 that takes care of currently
broken tests on aarch64 so the vmtest run passes.

This was tested by running:

LLVM_STRIP=llvm-strip-16 CLANG=clang-16 \
    tools/testing/selftests/bpf/vmtest.sh  -- \
        ./test_progs -d \
            \"$(cat tools/testing/selftests/bpf/DENYLIST{,.aarch64} \
                | cut -d'#' -f1 \
                | sed -e 's/^[[:space:]]*//' \
                      -e 's/[[:space:]]*$//' \
                | tr -s '\n' ','\
            )\"

on an aarch64 host.
