Feature: add sync message logging to log_per_node_statement and notice_per_node_statement

Previously pgpool did not emit logs for a "sync" message when
log_per_node_statement/notice_per_node_statement enabled. Although
"sync" is not a query statement, I think a sync message plays
important role in extended query protocol since it indicates the
completion of series of extended query protocol messages, and logging
a sync message is important in a trouble shooting (I myself often
enable debug message just to know whether a sync message is sent to
backend or not, but enabling debug message creates lots of noise).

This commit enable logging for a sync message to
log_per_node_statement and notice_per_node_statement.
