mdev: add -v to increase log verbosity
If logging to stderr and/or syslog the -v option can be given one or
more times to increase the log verbosity. If mdev is used as hotplug
helper the log level is fixed set to 2 if mdev.log is found an appended
because there is no possiblity to pass arguments to the hotplug helper.
