[PATCH] sstate: Allow switching between linux and non0-linux SDK builds within the same tmpdir

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

Currently if you try and switch between linux/darwin/mingw SDK builds in the
same TMPDIR, things break. This is due to sstate not reflecting the SDK_OS in 
the manifest names.

Since they are different, reflect this in the manifest naming and allow
this to work.
