While using the default Bazel C++ toolchain to build Yocto native tools
(bazel build --host_crosstool_top=@bazel_tools//tools/cpp:toolchain),
it failed with `bazel references a path outside of the execution root',
Add Yocto native sysroot dir (YOCTO_NATIVE_SYSROOT) to
builtin_include_directories could fix the issue
If not set YOCTO_NATIVE_SYSROOT, use NOT_SET_YOCTO_NATIVE_SYSROOT
to replace as a warning
Set YOCTO_NATIVE_SYSROOT in bazel.bbclass
