kill_art logic fails if "Message Queues" present

[corrodis]

The line below fails

artdaq-daqinterface/bin/mopup_shmem.sh

Line 116 in 82b9ff7

if ! [[ "$nattached" =~ ^[0-9]+$ ]]; then

for shmid 0 since my ipcs yields:

------ Message Queues --------
key        msqid      owner      perms      used-bytes   messages    
0xdeadbeef 0          root       660        0            0           

------ Shared Memory Segments --------

0xbb0af9ac 1          mu2ecrv    666        10486232   0                       

------ Semaphore Arrays --------
key        semid      owner      perms      nsems     

The 0 from the Message Queues and the Shared Memory Segments sections get confused, resulting in nattached not beeing 0 but 0 0.
