st/mesa: align cube map arrays layers

Browse source 
We create textures internally for texsubimage, and we use
the values from sub image to create a new texture, however
we don't align these to valid sizes, and cube map arrays
must have an array size aligned to 6.

This fixes texsubimage cube_map_array on CAYMAN at least,
(it was causing  GPU hang and bad values), it probably
also fixes it on radeonsi and evergreen.
