Fix the improper use of LOCAL_WHOLE_STATIC_LIBRARIES.

If two libraries both use LOCAL_WHOLE_STATIC_LIBRARIES and include a same
library, there would be linking errors when generating a shared library
(or executable) that depends on the two libraries both.

Also clean up Android.mk files.

Remove the "LOCAL_MODULE_TAGS := eng" line for the updater module. The
module will then default to "optional" which won't be built until needed.
