[PATCH] selftests/filesystems: include <fcntl.h> in wrappers.h

[Sasha Levin <sashal@kernel.org>]

openat_o_mkdir() in wrappers.h uses O_DIRECTORY, O_CREAT and O_EXCL, but
the header doesn't include <fcntl.h>. fscontext_ns_test.c doesn't
either, so it no longer builds:

  ../wrappers.h:116:32: error: 'O_DIRECTORY' undeclared

Include it in the header.

Every selftest that includes wrappers.h builds with this, gcc and clang
on x86_64.
