iris: Mark cbuf0 as not needing uploading every single time

Browse Source 
I neglected to mark cbuf0_needs_upload = false after uploading it.
The obvious fix regressed user clip plane tests, because of a second
bug: we also forgot to mark that they may need re-uploading when
changing shader programs (which may have more or less system values).

Thanks to Timur Kristóf for catching the original issue.
