POSIX message queues: Move mq_setattr() and mq_getattr() from nuttx/libc/mqueue to nuttx/sched/mqueue. Also add sysyscall support for mq_setattr() and mq_getattr(). This is necessary in protected and kernel builds because in those cases the message queue structure is protect and cannot be accessed directly from user mode code. Noted by Jouko Holopainen.
