Fix broken 'make distclean'

There is an error below when running 'make distclean':

Makefile:496: ../drm/.deps/va_drm_utils.Plo: No such file or directory
make[2]: *** No rule to make target '../drm/.deps/va_drm_utils.Plo'.
Stop.

The regression is caused by f17486f which added subdir-objects to
AM_INIT_AUTOMAKE.
