[PATCH] kernel: Clean DEPLOYDIR before do_deploy runs

[Richard Purdie <richard.purdie@linuxfoundation.org>]

If we don't do this, the deploy sstate object contains an every
increasing number of modules tarballs and kernel images, one per
execution of "-c deploy -f".

Cleaning the directory before we start makes things much tidier.
