Change-Id: I94fc9a580c95c3fae740a38842be6677dc3e4576
Cleanup: remove unused files, duplicate packages

1) AudioBTID.csv: only used by msm8660 qcom audio-caf, not 8960
2) Keylayouts: removed those provided by AOSP in
   frameworks/base/data/keyboards
3) Packages: make_ext4fs and setup_fs already built by common
