bpftool: Mount bpffs when pinmaps path not under the bpffs
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
[0] https://github.com/libbpf/bpftool/issues/146
Fixes: 3767a94b3253 ("bpftool: add pinmaps argument to the load/loadall")
