[pgpool-committers: 2777] pgpool: Fix possible hang-up of regression test 054.postgres_fdw

[Yugo Nagata]

Fix possible hang-up of regression test 054.postgres_fdw

In this test, psql acceses foreign table through backend node #1
like folowings:
 node #1 (PostgreSQL)-> pgpool -> node #0 (PostgreSQL)
For this purpose, node #1 should be detached from pgpool
to avoid closed loop. However, the node might not be detached yet
just after pcp_detach_node command. This caused the hang-up.

To fix this, sleep 1 is inserted after pcp_detach_node.
