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)
