Restore builtins.pathExists behavior on broken symlinks

Browse source 
Commit 83c067c0fa changed `builtins.pathExists`
to resolve symlinks before checking for existence. Consequently, if the path
refers to a symlink itself, existence of the target of the symlink (instead of
the symlink itself) was checked. Restore the previous behavior by skipping
symlink resolution in the last component.

(cherry picked from commit 89e21ab4bd)
