t0090: stop losing return codes of git commands

Browse Source 
In generate_expected_cache_tree_rec(), there are currently two instances
of `git ls-files` in the upstream of a pipe. In the case where the
upstream git command fails, its return code will be lost. Extract the
`git ls-files` into its own call so that if it ever fails, its return
code is not lost.
