Torture-test changes for 4.10

Hello!

This series contains a couple of torture-test changes:

1. Remove obsolete files from the rcutorture .gitignore file.

2. Prevent the --jitter flag from delaying --build-only runs.

Thanx, Paul

Currently, if the --jitter flag specifies jitter for a --build-only run, the system will obediently build a kernel, refuse to launch it, launch the requested number of jitter processes, and wait for the specified kernel run time, which defaults to 30 minutes. This is of course quite pointless.

This commit therefore disables jitter on build-only runs.
