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.
