Since we're now using aospless archive for meson.build, we can use headers from there and remove .ci/android_headers/ directory completely. Adding aospless cflags also raised some new tidy checks fails, which were fixed by this commit. Since clang-tidy now relies on aospless files, running CI on the host can't be supported and removed. Running CI within the docker container is the only option left. Signed-off-by: Roman Stratiienko <r.stratiienko@gmail.com>
