ART: Update art-tools modules for host

Use LOCAL_IS_HOST_MODULE rather than LOCAL_HOST_REQUIRED_MODULES. The
latter appears to imply a target module build with the listed host

Fixes Mac build breakage.

Bug: 129400556
Test: "python frameworks/rs/build_rs.py" on Mac
Test: m -j100 art-tools (and check out)
