pgsql: Lessen library-loading log level.

Lessen library-loading log level.

Previously, messages were emitted at the LOG level every time a
backend preloaded a library. That was acceptable (though unnecessary)
for shared_preload_libraries; but it was excessive for
local_preload_libraries and session_preload_libraries. Reduce to
DEBUG1.

Also, there was logic in the EXEC_BACKEND case to avoid repeated
messages for shared_preload_libraries by demoting them to
DEBUG2. DEBUG1 seems more appropriate there, as well, so eliminate
that special case.
