cbfs_core.c: make cfbs searches even less verbose

The cbfs core code would print out the name of the file it is
searching for and when it is found would print out the name
again. This contributes to a lot of unnecessary messages in a
functioning payload’s output. Change this message to a DEBUG one
so that it will only be printed when CONFIG_DEBUG_CBFS is enabled.
