Makes 'GPSD' SHM export exclusive.
If multiple copies of gpsd share a single SHM export (e.g., during
regression tests without the previous fix), then the result is just a
confusing mess. Adding the "exclusive" option to shmget() fixes this
by making it fail. Note that the failure becomes a failure of
shm_acquire(), which is currently ignored.
TESTED:
Prior to making the regression test fix for unique SHM IDs, verified
that parallel regression tests got the expected failures, while
non-parallel tests passed.
