Move vendor files to proprietary/vendor

My experience is running setup-makefiles.sh breaks the build with the current
configuration. This better reflects where files are going anyway.

Also deleted unused alsa.omap3.so.

Move vendor files to proprietary/vendor
Merge branch 'jellybean-encore' into cm-10.1
Don't ship audio components from the vendor blobs tree

All of these components are either obsolete or built from freely
available source, so it makes no sense to ship them with the proprietary
blobs.
Merge pull request #5 from steven676/cm-10.1

encore: remove obsolete files, sync with extract-files.sh
