Revert "tools: cpplint: Add Android.bp to build cpplint as python_binary_host"

This reverts commit dfda9bcf07fbab25efe44fe603f6ebe9ed643ea7.

Reason for revert: The development flow & goals of repohooks is unable
to support the needs of art.  The main branch of repohooks is used in
all branches of Android, including very old ones, so we have to stay
compatible.  That means the tool behavior, and in Android.bp syntax.
Older branches will fail with newer cpplint, and older soong tooling
does not recognize newer keywords in this Android.bp.

Any tools we want to execute at build time will need to be vendored in
directly in external/ so they stay pinned/locked when branches are cut.
