    glamor: Fix GLES2 non-VBO temporary memory allocation.
    
    We'd get a request for like 16 bytes, claim to have allocated
    GLAMOR_VBO_SIZE, and then not reallocate when something a request
    bigger than 16 came along.  The intent was to always allocate at least
    GLAMOR_VBO_SIZE.
    
    Fixes segfaults with Xephyr -glamor_gles2 and running gnome-terminal.
