Caleb White 08830ac00f worktree: add test for path handling in linked worktrees
A failure scenario reported in an earlier patch series[1] that several
`git worktree` subcommands failed or misbehaved when invoked from within
linked worktrees that used relative paths.

This adds a test that executes a `worktree prune` command inside both an
internally and an externally linked worktree and asserts that the other
worktree was not pruned.
