perlPackages.NetRemctl: remove failing test

Remove t/backend/options.t as one of its tests fail. Seems benign.

  Failed test '...and correct error'
  at t/backend/options.t line 97.
         got: 'number: value "foo" invalid for option number (integer number expected)'
    expected: 'number: value "foo" invalid for option number (number expected)'
