ecpg/ecpglib must build the src/port files it uses with -DFRONTEND.

Remarkably, this hasn't been noticed before, though it surely should have been happening since around the fall of the Byzantine empire. Commit 438b529 changed path.c to depend on FRONTEND, and that exposed the omission, per buildfarm reports. I'm suspicious that some other subdirectories are missing this too, but this one change is enough to make ecpg tests pass for me.
