Mike Rapoport 6f6a841fb7 selftest/vm: add helpers to detect PAGE_SIZE and PAGE_SHIFT ...

PAGE_SIZE is not 4096 in many configurations, particularly ppc64 uses 64K
pages in majority of cases.

Add helpers to detect PAGE_SIZE and PAGE_SHIFT dynamically.

Without this tests are broken w.r.t reading /proc/self/pagemap

    if (pread(pagemap_fd, ent, sizeof(ent),
              (uintptr_t)ptr >> (PAGE_SHIFT - 3)) != sizeof(ent))
              err(2, "read pagemap");
