Fix postgis_tiger_geocoder.control generation

Patch by Christoph Berg

Commit 639308e9 moved the postgis_tiger_geocoder.control into the 
Makefile, but forgot to remove the file from configure.ac, which still 
generates the file, so the Makefile rule is not effective and the 
resulting .control file has the raw @EXTVERSION@ line from the .in file.
