app_directed_pickup.c: Change some log messages from NOTICE to VERBOSE.

UpgradeNote: In an effort to reduce log spam, two normal progress
"pickup attempted" log messages from app_directed_pickup have been changed
from NOTICE to VERBOSE(3).  This puts them on par with other normal
dialplan progress messages.
