t3427: accelerate this test by using fast-export and fast-import
fast-export and fast-import can easily handle the simple rewrite that was being done by filter-branch, and should be faster on systems with a slow fork. Measuring the overall time taken for all of t3427 (not just the difference between filter-branch and fast-export/fast-import) shows a speedup of about 5% on Linux and 11% on Mac.
