meta: Use the DrawBuffer's stencil size

Previously the code was erroneously using the stencil size of the
context instead of the stencil size of the DrawBuffer.  With FBOs
these may be different.  As a result, clearing the stencil buffer of
an FBO bound to a context that doesn't have stencil would fail.
