[PATCH] selftests/mqueue: fix timespec printf format specifiers

[zhangchujun]

The tv_nsec members of struct timespec are signed long values on
the target Linux ABI, but mq_perf_tests.c prints them using %lu.

Use %ld to match the argument type when printing the clock
resolution and the TEST1 and TEST2 timing summaries.
