Recent Ubuntu releases (e.g. 15.10) include the Wacom driver in their
initramfs. If a tablet is connected at boot, this driver will be loaded
in preference to whatever we may have installed to /lib/modules. Since
we can't prevent this from occuring, we need to update the initramfs
to contain our module. Thankfully, Ubuntu provides a command to do just
that: update-initramfs. By running this after the module is installed
and depmod updated, the initramfs will be updated to contain our on-disk
driver and load it on boot.

Changes from v1:
* update-initramfs allows you to provide a kernel version parameter
"-k". Use it to ensure the correct initramfs is rebuilt.
