[PATCH v1 5/5] tools/mm/page-types.c: hide compound pages in non-raw mode

From: Naoya Horiguchi <naoya.horiguchi@nec.com>

In non-raw mode (i.e. calling page-types without -r flag), any flags
for compound pages except for hugetlb are supposed to be hidden.
But currently KPF_THP is shown and the newly added flag KPF_FOLIO is
also shown, which is unexpected. So hide them.
