ouidb: use full device vendor names
Our pre processed oui database file use only partial names - first word of the manufacture full name.
Actual notification message:
New device appeared on your network (MAC address aa:bb:cc:11:22:33, vendor Hewlett)
while ideally it should look like:
New device appeared on your network (MAC address aa:bb:cc:11:22:33, vendor Hewlett Packard)
This could be most likely fixed by adjusting this regex: https://gitlab.nic.cz/turris/os/packages/-/blob/master/utils/ouidb/Makefile#L33
