ANDROID: Suppress build.sh deprecation warnings.

build.sh will continued to be supported in android13-*
branches. To avoid confusion, suppress the deprecation
warnings when executing build.sh on android13-*.

This change also avoids the time delay for inferring
the equivalent Bazel command.

It is still encouraged to migrate build.sh to Bazel.

Test: manually execute build.sh, no deprecation warnings
