Patch 1-3 fix some problem about bpf selftests. Patch 4 add local rootfs
image support for vmtest. Patch 5 enable cross-platform testing for
vmtest. Patch 6-10 enable vmtest on RV64.

We can now perform cross platform testing for riscv64 bpf using the
following command:

PLATFORM=riscv64 CROSS_COMPILE=riscv64-linux-gnu- \
  tools/testing/selftests/bpf/vmtest.sh \
  -l <path of local rootfs image> -- \
  ./test_progs -d \
      \"$(cat tools/testing/selftests/bpf/DENYLIST.riscv64 \
          | cut -d'#' -f1 \
          | sed -e 's/^[[:space:]]*//' \
                -e 's/[[:space:]]*$//' \
          | tr -s '\n' ',' \
      )\"

For better regression, we rely on commit [0] [1]. And since the work of riscv
ftrace to remove stop_machine atomic replacement is in progress, we also
need to revert commit [2] [3].

The test platform is x86_64 architecture, and the versions of relevant
components are as follows:
    QEMU: 8.2.0
    CLANG: 17.0.6 (align to BPF CI)
    ROOTFS: ubuntu noble (generated by [4])
