Subject: [PATCH] Linux: fix log message that was being unconditionally sent to stderr (#44)

This message was put in place to aid libusb-compat-0.1 users, who
may run into the change that libusb-0.1 allowed you to usb_open() a
device that you don't have write access to, but libusb-1.0 does not.

As explained on the ticket this change is dangerous so it should go through
the usual logging mechanism. I also added a similar regular log message
to libusb-compat-0.1.

Resolves: #628356
