chore(nix/buildkite): Drop --fork-point parameter

Browse source 
The --fork-point parameter is dependent on reflog data which may get
garbage collected. This can lead to flaky behaviour where it returns
no results and fails if `git gc` recently ran (Buildkite will do this
occasionally).

Though the parameter is semantically closer to what we're looking for,
the output is *usually* the same commit since we're not dealing with
more than one thing to compare.
