android: fix vulkan build issues with anv_entrypoints

Patch fixes entrypoint generation for libmesa_anv_entrypoints that
still used old style of calling generator script.

Also small fixes to libmesa_vulkan_common where there was a typo
in target name (vulknan) and files were generated to wrong folder.

Fixes: 8211e3e6 ("anv: Generate anv_entrypoints header and code in one command")
