Better aidl generated dependency
Previously if an imported aidl file has been deleted or moved,
the generated dependency file still contains the stale file name,
and make will fail with "No rule to make target <the deleted/moved
file>".
This change uses technique described in section "Automatic Dependency
Generation", Chapter 8 of "Managing Projects with GNU Make (3d
Edition)".
The same technique is used by the Android platform build system to
generate C/C++ header dependencies.
