[PATCH hwc] Android: add CleanSpec.mk

[PATCH hwc] Android: add CleanSpec.mk

[Chih-Wei Huang]

The file contains rules that are executed on incremental builds.
Since commit 4f7dc9b6 the library was moved to /vendor so
the old file must be removed.

Seems a bit silly to add forever an explicit file to clean for a
transient problem.

The problem is people usually won't notice
the libraries have been moved to /vendor.
In an incremental build the old files still
exist in /system that may cause issues.

It's necessary unless you have a better idea
to tell people "hey, you need to do a clean build".

While transient, if maintaining multuple Android versions it may still
stick around for quite some time.

That being said, I don't have much of an opinion about this.

That's not the issue. Once you do a clean build, the problem is gone
regardless of version.
