Make create postgis and postgis_topology unpackaged script automated

[robe]

Right now to generate the postgis--unpackaged.sql.in postgis-topology--unpackaged.sql.in

I just run a the "make_unpackaged.sql" query against a newly installed database with postgis / postgis_topology extensions. This I'd like to automate either by sourcing the sql files or as a autocommit job on Jenkins that will auto post whenever a change to the repo is made.
