app-crypt/libu2f-host: create the group 'plugdev' if necessary #564748

This ebuild installs a udev rule that creates matching hidraw nodes
with the group 'plugdev' for non-systemd configurations. However, it
does not create the group if it doesn't exist, causing attached
devices to fail permission checks.
