    scripts/gdb/proc: add struct mount & struct super_block addr in lx-mounts command

    This is many times found useful while debugging some FS related
    issue.

    <e.g. output>
          mount          super_block     devname pathname fstype options
    0xffff888a0bfa4b40 0xffff888a0bfc1000 none / rootfs rw 0 0
    0xffff888a033f75c0 0xffff8889fcf65000 /dev/root / ext4 rw,relatime 0 0
    0xffff8889fc8ce040 0xffff888a0bb51000 devtmpfs /dev devtmpfs rw,relatime 0 0
