From: Nathan Froyd <froydnj@codesourcery.com>

mqueue.h is only available if __NR_mq_open is defined.  So don't include
it unconditionally.  Similarly, the mq_* family of syscalls depend on
__NR_mq_open.  Finally, the copy_{from,to}_user_mq_attr functions should
not be defined unconditionally, but only if we're going to use the mq_*
syscalls.
