Colin Cross af9c55b780 Correctly add dependencies to java_resource_dirs files
java_resource_dirs was using a file list file that was generated
at ninja time to get the list of files to include, which meant
there were no dependencies on the files to cause res.jar to get
rebuilt.  Switch to using a glob at soong time instead.  This
is substantially similar to a glob in java_resources, except that
java_resource_dirs strips the listed directories off the paths
that end up in the jar.

Test: TestResources in java_test.go
