pyenv: New version 20130613

The pyenv version is the date-like part.
The file is v0.4.0-20130613.tar.gz and the
0.4.0 part is taken from upstream rbenv, so
that pyenv is the latter part.

Homebrew currently autodetects only the
last part, so we don't have to explicitly
set the version.

Closes #20462.

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.

Closes #20423.
