generate_firmware_task: implement support for --list-filenames 

Treat the output file argument specifically when it's “--list-filenames”:
instead of actually generating a task file with a list of packages (and a
few comments), output the Filename field for each firmware package
matching our criteria.

Move some status messages to STDERR accordingly.

This makes the “find suitable firmware packages” reusable, e.g. by
make-firmware-image.
