Subject: [PATCH] Remove "check_build_deps" build steps

When building with Bitbake, we want Bitbake to manage our dependencies,
so we remove the "check_build_deps" steps from Perfetto.

Also setting "is_cross_compiling" to true, so that the host-side tools
(such as protoc) will always be generated using the native toolchain,
rather than the Bitbake-generated one.
