Fix OWNERS to contain actual owners

Since there is no androidx-main branch on platform/build/soong,
I believe the current OWNERS file is effectively empty, blocking
all edits, which is sad.

This branch is for only the build-tools needed for building and
testing androidx (currently just nsjail and dependencies)
