[pgpool-committers: 8525] pgpool: Fix shared memory allocation function.

[Tatsuo Ishii]

Fix shared memory allocation function.

pool_shared_memory_segment_get_chunk() which is responsible for shared
memory allocation, failed to consider request size alignment. If
requeste size is not in MAXALIGN (typically 8) bytes, it could overrun
the shared memory area. Probably harmless in the wild but better to
fix.
