Modify the existing unit test (from libkqueue) which already exercises process events via fork() and kill(). Now, the child process simply checks that the 'kqfd' descriptor is invalid. Some minor modifications were required to make err() work correctly. It seems that this test was imported using the output of a configure script, but config.h was not included in key places, nor was its syntax correct (need '#define HAVE_FOO 1' rather than '#define HAVE_FOO'). Finally, change main() to run the "proc" suite by default, but widened the '#if TODO' in proc.c to include the non-functioning test event_trigger().
