[Impact]
While debugging bug 1910277, I found that the test compilation will print some warnings:
  memfd_test.c:64:7: warning: implicit declaration of function ‘open’;
  memfd_test.c:90:6: warning: implicit declaration of function ‘fcntl’
  memfd_test.c:397:6: warning: implicit declaration of function ‘fallocate’;
  fuse_test.c:67:6: warning: implicit declaration of function ‘fcntl’
  fuse_test.c:261:7: warning: implicit declaration of function ‘open’;

[Fix]
* 1c49e3783f8899 ("selftests/memfd: Fix implicit declaration warnings")

[Test Case]
Build the memfd test in kselftests with:
  sudo make TARGETS=memfd

With this fix, these warnings will be gone.

[Where problems could occur]
This fix is just for fixing the test case compilation, it's beyond my imagination to see where the potential problems lies within.
