Fix duplicate NodeTag enum in nodes.h.HEADmaster

The file was imported from PostgreSQL and Pgpool-II specific node type
were added right after T_Invalid = 0, then nodetags.h is
included. Since nodetags.h explicitly assign values to each enum
starting from 1, and this created duplicated enums.
T_List = 1,
T_Alias = 2,
T_RangeVar = 3,
T_PgpoolVariableSetStmt, (1)
T_PgpoolVariableShowStmt, (2)
T_PgpoolQueryCacheStmt, (3)

Although fortunately this seems does not create any trouble except the
duplicated enums, this should be fixed: moving the inclusion of
nodetags.h right after "T_invalid = 0".
