pixman: upgrade to 0.32.4

Drop the generic C implementation of pixman_blt patch, upstream refuses to
accept generic implementations as the policy is that the caller provides generic
paths, and this patch was only used in conjunction with a matching patch in
xserver-xorg which we don't carry anymore.

-Generic C implementation of pixman_blt with overlapping support
-
-This was ported from meta-oe's patch [1]:
-Uses memcpy/memmove functions to copy pixels, can handle the
-case when both source and destination areas are in the same
-image (this is useful for scrolling).
-
-It is assumed that copying direction is only important when
-using the same image for both source and destination (and
-src_stride == dst_stride). Copying direction is undefined
-for the images with different source and destination stride
-which happen to be in the overlapped areas (but this is an
-unrealistic case anyway).
