  path: extract function to check whether a path supports symlinks
  
  When initializing a repository, we need to check whether its working
  directory supports symlinks to correctly set the initial value of the
  "core.symlinks" config variable. The code to check the filesystem is
  reusable in other parts of our codebase, like for example in our tests
  to determine whether certain tests can be expected to succeed or not.
  
  Extract the code into a new function `git_path_supports_symlinks` to
  avoid duplicate implementations. Remove a duplicate implementation in
  the repo test helper code.
