Several C programs fail to include the headers declaring all the
functions they call, resulting in warnings or errors.
After this, memfd_test.c is still missing some function declarations
but can't easily get them because of a conflict between
<linux/fcntl.h> and <sys/fcntl.h>.

There is a mandate of 16-byte aligned stack on AArch64 [1], so the
STACK_SIZE here should also be 16-byte aligned, otherwise we would
get an error when calling clone().

This test currently fails on 32-bit systems since we use u64 type to pass the
flags to fcntl.
This commit changes this to use 'unsigned int' type for flags to fcntl making it
work on 32-bit systems.

Some basic tests to verify sealing on memfds works as expected and
guarantees the advertised semantics.
