[10/13] t4014: remove confusing pipe in check_threading()

Commit Message

In check_threading(), there was a Git command in the upstream of a pipe.
In order to not lose its status code, it was saved into a file. However,
this may be confusing so rewrite to redirect IO to file. This allows us
to directly use the conventional &&-chain.
