t3302-notes-index-expensive: Speed up create_repo()

Browse source 
Creating repos with 10/100/1000/10000 commits and notes takes a lot of time.
However, using git-fast-import to do the job is a lot more efficient than
using plumbing commands to do the same.

This patch decreases the overall run-time of this test on my machine from
~3 to ~1 minutes.
