Craig Small 9c5397a941 testsuite: Add check for shared memory
Created a test process test_shm that allocates a shared memory
segment and prints the segment ID. pmap testsuite runs pmap to
check that the segment is found.

The value returned by shmget() is the same value that is printed
in the fifth column /proc/<PID>/maps
