Apply LOCAL_LDLIBS to target build rules too.

Use LOCAL_LDLIBS to link against prebuilt libraries (such as NDK
libraries).
Previously LOCAL_LDLIBS only applies to host modules and the behaviour
confuses users.

Add tool to package up built modules.

With this change, you can package up modules while avoiding installing
them to the system.img or userdata.img.
- build/core/tasks/tools/package-modules.mk
  You can use this template to package up modules into a zip file and
  preserve the installed file paths.
- LOCAL_PICKUP_FILES, you can use this variable to package up extra
  files/directories.

Target "tests" now only builds the modules tagged as "tests"

But not install them.
This prevents "make tests" polluting system.img or userdata.img.
We have new mechanism to build and package up modules into zip file in
build/core/tasks/tools.
Change package-modules.mk to install DATA/ instead of data/ in the
zip file; Better handle of module name conflicting.
