Don't allow data_directory to be set in postgresql.auto.conf by ALTER SYSTEM.
data_directory could be set both in postgresql.conf and postgresql.auto.conf so far. This could cause some problematic situations like circular definition. To avoid such situations, this commit forbids a user to set data_directory in postgresql.auto.conf. Backpatch this to 9.4 where ALTER SYSTEM command was introduced. Amit Kapila, reviewed by Abhijit Menon-Sen, with minor adjustments by me.
