Stop including version_defaults.mk

version_defaults.mk is part of the core build system, and not
intended for including by modules.  It is guaranteed to have
already been included before any Android.mk files have been
read.  Including it twice causes HAS_BUILD_NUMBER to be set
to true which causes incremental rebuilds to reread all the
makefiles:
$(file <out/build_number.txt) was changed, regenerating...

Also fix the unnecessary $(info) messages that clutter the
build output.

Test: m nothing && m nothing
