Android: Remove --wait-for-java-debugger Chrome flag

It's superseded by the --wait-for-java-debugger wrapper script flag.

The wrapper scripts use "am set-debug-app -w", which cause the
debugger to attach before any application code has been loaded
and is much more useful since it allows breakpoints during
start-up.
