[Mesa-dev] android: fixes for anv build

[Mauro Rossi]

Hi, I'm sending a series of fixed for anv build

[PATCH 1/3] android: anv/extensions: fix generated sources build
[PATCH 2/3] android: anv: add dependency on libnativewindow for O and
[PATCH 3/3] android: vulkan/util: add dependency on libnativewindow

Since anv now implements vulkan HAL, the build was tested by
installing anv vulkan.$(TARGET_BOARD_PLATFORM) module with oreo-x86

Patches are also proposed as candidates for 18.0 mesa-stable branch,
for mesa 18.0.0 release

Kind regards
Mauro
