Add missing index (update spy_queue.schema.xml)

Add missing index to spy_queue_process.process_pid

Queries to find processes by process id in Spryker's queue process manager use condition SELECT/DELETE FROM spy_queue_process WHERE process_pid IN (...), but column process_pid doesn't have an index, so DB performance of those queries is worse than it needs to be, especially when the table size grows (which should not, but might happen).
