[buck] stop supporting the pre-genrule Java integration

Summary:
You should use `--buck-java` instead, which uses the new "genrule
master" integration.

This diff makes it impossible to select the previous integration.
Upcoming diffs will clean up the resulting dead code.

This also make infer fail hard when no buck mode is specified in a buck
capture command, eg `infer -- buck build //foo:foo`. The reason is that
we need to choose between 3 incompatible integrations and making any of
them the default will confuse at least one person in the future.
