[PATCH for-next v3] selftests/mm: Add a few missing gitignore files

[Li Zhijian <lizhijian@fujitsu.com>]

Compiled binary files should be added to .gitignore
'git status' complains:
   Untracked files:
   (use "git add <file>..." to include in what will be committed)
         mm/hugetlb_dio
         mm/pkey_sighandler_tests_32
         mm/pkey_sighandler_tests_64
