Remove GUC_NOT_IN_SAMPLE from enable_self_join_elimination

Browse Source 
fc069a3a63 implements Self-Join Elimination (SJE) and provides a new GUC
variable: enable_self_join_elimination.  This new GUC variable was marked
as GUC_NOT_IN_SAMPLE.  However, enable_self_join_elimination is documented
and is not different from any other enable_* GUCs.  Thus, remove
GUC_NOT_IN_SAMPLE from it and add it to the postgresql.conf.sample.
