Ignore more environment variables in pg_regress.c

Browse Source 
This is similar to the work done in 8279f68 for TestLib.pm, where
environment variables set may cause unwanted failures if using a
temporary installation with pg_regress.  The list of variables reset is
adjusted in each stable branch depending on what is supported.

Comments are added to remember that the lists in TestLib.pm and
pg_regress.c had better be kept in sync.
