Rename keymaster_device_t to keymaster0_device_t.

This is to accomodate the new keymaster1_device_t, which has an entirely
different interface.

Soon I'll provide a libkeymaster which provides a unified (and nicer)
interface for dealing with both v0 and v1 keymaster implementations
using a v1 keymaster API.  For now this change is just so that vold will
build and run.
