update node-test-commit-v8-linux to not overwrite make-v8.sh with a local copy

Follow on from #1536, cc @refack @mhdawson

https://ci.nodejs.org/job/node-test-commit-v8-linux/ is copying over make-v8.sh from a local copy, with a note about upstreaming the changes.

But @refack already upstreamed the changes.

I modified the job config to not do the copy, I'll see how it goes: https://ci.nodejs.org/job/node-test-commit-v8-linux/2391/

I don't want to carry this hack over onto the new centos7 ppcle machines.

+1 if the file is the same. I had thought that @refack had upstreamed.

Also TBD: The test-osuosl-ubuntu1404-ppc64 have copies of the pkg-config files in /home/iojs/build-tools/pkg-config-files, but the are identical to the system .pc files in /usr/lib/powerpc64le-linux-gnu/pkgconfig, they can be removed and the jenkins and make-v8.sh scripts simplified.

https://ci.nodejs.org/job/node-test-commit-v8-linux/2396/nodes=centos7-ppcle,v8test=v8test/console Its actually building v8, that's promising, will take a while to know if it suceeds in the test.

been more than a month with no complaints, must have worked.
