android: anv/extensions: fix generated sources build

Building rules are aligned to automake ones

The correct script to build anv_extensions.{c,h} is anv_extensions_gen.py
Generation rules for anv_extensions.c requires --out-c option
Generation rules for anv_extensions.h were missing
Necessary include paths are added to avoid following build errors:

cp: cannot stat '.../gen/STATIC_LIBRARIES/libmesa_vulkan_common_intermediates/vulkan/anv_extensions.c':
No such file or directory
