Drive: rename Interface to interface

Drive.Interface.yaml is not being processed and no server.hpp
is created.  Renamed to Drive.interface.yaml instead.

Fixes openbmc/phosphor-dbus-interfaces#11.

Same change as in
https://gerrit.openbmc-project.xyz/c/openbmc/phosphor-dbus-interfaces/+/43632
but that change was removed due to
https://gerrit.openbmc-project.xyz/c/openbmc/phosphor-dbus-interfaces/+/43821
