Use correct size of segment for shared-mem export
The gpsd exports data to clients via shared-memory using
struct shmexport_t, which contains both a copy of
struct gps_data_t and additional fields. However, when
allocating shared memory via shmget(), it was passing
sizeof(struct gps_data_t) as size of the whole segment.
The bug may cause gpsd crash in case the size of gps_data_t
is equal to or slightly smaller than a multiple of PAGE_SIZE.
