tools subcmd: Add missing NORETURN define for parse-options.h

parse-options.h uses the NORETURN macro without defining it.  perf
doesn't see a build error because it defines the macro in util.h before
including parse-options.h.  But any other tool including it will see an
error.

Define the macro in parse-options.h (if not already defined) so that
other tools can include it.
