Merge #17329: linter: Strip trailing / in path for git-subtree-check

60582d6060542c1e3a23141ea825e36818fbbd54 [linter] Strip trailing / in path for git-subtree-check (John Newbery)

Pull request description:

  git-subtree-check fails if the directory is given with a trailing slash,
  eg:

  ```
  > test/lint/git-subtree-check.sh src/univalue/
  ERROR: src/univalue/ is not a subtree
  ```

  Shell autocompletes will add the trailing slash when autofilling the
  path name, which will therefore cause the script to fail.

  Just ignore any trailing slash.
