Subject: [PATCH] selftests/memfd: Fix unknown type name build failure

Partially backport v6.3 commit 11f75a01448f ("selftests/memfd: add tests
for MFD_NOEXEC_SEAL MFD_EXEC") to fix an unknown type name build error.
In some systems, the __u64 typedef is not present due to differences in
system headers, causing compilation errors like this one:

fuse_test.c:64:8: error: unknown type name '__u64'
   64 | static __u64 mfd_assert_get_seals(int fd)

This header includes the  __u64 typedef which increases the likelihood
of successful compilation on a wider variety of systems.
