[Raring] enable g_serial gadget by default on nexus7

[Oliver Grawert]

since we would like to offer a debugging shell on the nexus7 so that
devs do not always need to install openssh-server. 

switching the android gadget over to g_serial and providing a serial
console upstart job for it will make serial support work via the USB
cable, so please ajdust the nexus7 config according to the diff
below ...

the necessary upstart job will be shipped by the ubuntu-defaults-nexus7
package.
