Switch android tools' use of options parser to a more concise form for the single options-base case.

This is to prepare the options parser from making options parser creation exceptions a caught exception. Since all of these classes already have a single options class and used parseAndExitUponError, this allows us to keep behavior consistent between the malformed options-base errors and the incorrect user-input errors.

All the other uses of the options parser in //src/tools already throw sufficiently broad exceptions to not need this.
