Make Unicode makefile parallel-safe
Fix the rules so that each rule is parallel safe, using the same trickery that we use elsewhere in the tree for rules that produce more than one output file. Refactor the whole makefile so that there is less repetition. Discussion: https://www.postgresql.org/message-id/18e34084-aab1-1b4c-edd1-c4f9fb04f714%40enterprisedb.com
