Carlos Llamas 28eed9906e selftests/mm: cleanup -Wformat issues in hugetlb-mmap 
Commit ae571cd601 ("selftests/mm: hugetlb-mmap: add setup of HugeTLB
pages") and commit 9c5a65f374 ("selftests/mm: merge map_hugetlb into
hugepage-mmap") added logs of 'hugepage_size' which has a size_t type.
However, the incorrect format specifier '%lu' was used which triggers
-Wformat warnings when building for 32-bit:

  hugetlb-mmap.c:125:55: warning: format specifies type 'unsigned long'
  but the argument has type 'size_t' (aka 'unsigned int') [-Wformat]
    125 | ksft_print_msg("Default size hugepages (%lu kB)\n", hugepage_size >> 10);
        |                                         ~~~         ^~~~~~~~~~~~~~~~~~~
        |                                         %zu

  hugetlb-mmap.c:134:47: warning: format specifies type 'unsigned long'
  but the argument has type 'size_t' (aka 'unsigned int') [-Wformat]
    134 | ksft_exit_skip("Not enough %lu Kb pages\n", hugepage_size >> 10);
        |                            ~~~              ^~~~~~~~~~~~~~~~~~~
        |                            %zu

Fix this by switching to the expected '%zu' format specifier.
