Fixed and uncommented entry maker function

[doubleloop]

Previous commented function was overcomplicated. It constructed return dictionary using setmetatable and object with custom __index. I know this was taken straight from the telescope source code but this dictionary can be just constructed directly. Also fixed path usages.

@doubleloop it can also be path_display = { shorten = 5 } as specified in :h telescope.defaults.path_display and parsed at https://github.com/nvim-telescope/telescope.nvim/blob/master/lua/telescope/utils.lua#L285-L325
