mesa: Fix glGetVertexAttribi(GL_VERTEX_ATTRIB_ARRAY_SIZE)

Browse source 
mesa currently returns 4 when GL_VERTEX_ATTRIB_ARRAY_SIZE is queried
for a vertex array initially set up with size=GL_BGRA. This patch
makes changes to return size=GL_BGRA as required by the spec.

Fixes Khronos OpenGL CTS test: vertex_array_bgra_basic.test

V2: Use array->Format instead of adding a new variable
