plugins: load directories that are symlinks (#2214)

Fix issue where symlinked plugin directories were ignored. For example

    $ file ~/.config/micro/plug/example
    example: symbolic link to <target directory>

This allows plugins to be managed in a user's "dotfiles" repository, and
be symlinked into micro's plugin directory.
