USB Serial: Add simple install script
USB Serial: Add simple install script

The install script builds and installs the raiden module, it also copies
the udev rules file into /etc/udev/rules.d and updates the module alias
and dependency information.

The install script will also retrigger udev to process rules for all
devices that have the Google Vendor ID (0x18d1).  This ensures that
any devices that are connected when the install is run will immediately
be available for use (as opposed to requiring that these devices be
unplugged and replugged before use).
