  [AIX] Generate unique module id based on Pid and timestamp

A unique module id, which is a part of sinit and sterm function names, is
necessary to be unique. However, `getUniqueModuleId` will fail if there is
no strong external symbol within a module. We turn to use Pid and timestamp
when this happens.
