linux: Fix mq_timereceive check for 32 bit fallback code (BZ 29304)
On success, mq_receive() and mq_timedreceive() return the number of bytes in the received message, so it requires to check if the value is larger than 0. Checked on i686-linux-gnu. (cherry picked from commit 71d87d85bf54f6522813aec97c19bdd24997341e)
