Update twisted version in webkitpy.thirdparty.autoinstalled module.
https://bugs.webkit.org/show_bug.cgi?id=154667
Reviewed by Ryosuke Niwa.
Use twisted_15_5_0 for the twisted module used by run-benchmark because there is a bug in twisted 12.1.0 which sometimes stops the test.
Installing twisted was introduced in https://bugs.webkit.org/show_bug.cgi?id=147082 for run-benchmark script.
Since buildbot relies on twisted 12.1.0 and has not been verified the compatibility on twisted 15.5.0, it would be more secure to use an individual version for run-benchmark script.
