Title: Fix bug in `brew list --pinned`

Pinned formulae which were pinned at a previous version but then upgraded would not be listed by `brew list --pinned`. This is due to the good old "File.exist? thinks broken symlinks don't exist" gotcha, so the test in the select block in list_pinned has been changed to check if the pin file exists _or_ is a symlink.
