UXA: Declare glyph cache picture as component-alpha when necessary.
Without this, rendering component-alpha glyphs may break without a mask.
Bug #19534. Ported from fix by Michel Dänzer <daenzer@vmware.com> in
xserver commit 639f289dcdbe00a516820f573c01a8339e120ed4
(cherry picked from commit c80f1a9c5131721eaf87d12a7a67e603cdfed63b)
