selftests/mqueue: fix 5 warnings about signed/unsigned mismatches

When building with clang, via:

make LLVM=1 -C tools/testing/selftest

...clang warns about several cases of using a signed integer for the
priority argument to mq_receive(3), which expects an unsigned int.

Fix this by declaring the type as unsigned int in all cases.

testing/selftests/mqueue: Fix mq_perf_tests to free the allocated cpu set

The selftest "mqueue/mq_perf_tests.c" use CPU_ALLOC to allocate
CPU set. This cpu set is used further in pthread_attr_setaffinity_np
and by pthread_create in the code. But in current code, allocated
cpu set is not freed.

Fix this issue by adding CPU_FREE in the "shutdown" function which
is called in most of the error/exit path for the cleanup. There are
few error paths which exit without using shutdown. Add a common goto
error path with CPU_FREE for these cases.

selftests: mqueue: return Kselftest Skip code for skipped tests

When mqueue test is skipped because of unmet dependencies and/or
unsupported configuration, it exits with error which is treated as
a fail by the Kselftest framework. This leads to false negative
result even when the test could not be run.

Change it to return kselftest skip code when a test gets skipped to
clearly report that the test could not be run.

Change it to use ksft_exit_skip() when the test is skipped.

selftests: Add missing #include directives

Several C programs fail to include the headers declaring all the

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>.
