Subject: 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

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