qt5base: Patch Qt config to detect sunxi-mali

Currently Qt 5.5 only detects and build the eglfs_mali device
integration if the commercial Mali driver package from ARM is used.
This patch makes sure the Qt configure script also test for the
sunxi-mali driver package. It also removes the dependency of
the proprietary fbdev_window.h.

This issue is set to be fixed in upcoming Qt 5.6:

[Thomas: renumber patch from 0010 to 0009.]

[Thomas: build tested before the patch, verified that indeed the
eglfs-mali plugin doesn't get built, and that after the patch it gets
built as expected.]
