fs_procfsproc：Fix the wrong position of information display, integrate the fd information of socket and file 

By left-aligned display, the effect is as follows (0, 1, 2 is fd information, 3 is sd information)

    FD  OFLAGS  TYPE POS       PATH
    0   3       1    0         /dev/console
    1   3       1    0         /dev/console
    2   3       1    0         /dev/console
    3   65      2
