Tao Chen 77bf25dab8 bpftool: Mount bpffs when pinmaps path not under the bpffs
[ Upstream commit da5f8fd1f0 ]

As Quentin said [0], BPF map pinning will fail if the pinmaps path is not
under the bpffs, like:

  libbpf: specified path /home/ubuntu/test/sock_ops_map is not on BPF FS
  Error: failed to pin all maps
