csource, executor: add usb emulation feature
The feature gets enabled when /dev/raw-gadget is present and accessible.
With this feature enabled, executor will do chmod 0666 /dev/raw-gadget on
startup, which makes it possible to do USB fuzzing in setuid and namespace
sandboxes. There should be no backwards compatibility issues with syz
reproducers that don't explicitly enable this feature, as they currently only
work in none sandbox.
