selftests/bpf: Initial DENYLIST for aarch64

Those tests are currently failing on aarch64, ignore them until they are
individually addressed.

Using this deny list, vmtest.sh ran successfully using

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' ','\
            )\"
