Naoya Horiguchi b76901db7b tools/vm/page-types.c: move show_file() to summary output 
Currently file info from show_file() is printed out within page list
like below, but this is inconvenient a little to utilize the page list
from other scripts (maybe needs additional filtering).

    $ ./page-types -f page-types.c -l
    foffset offset  len     flags
    page-types.c Inode: 15108680 Size: 30953 (8 pages)

With this patch file info is printed out in summary part like below:

    $ ./page-types -f page-types.c -l
    foffset offset  len     flags
