Use more compact format for snippet menus

Browse Source 
* yasnippet-tests.el (yas-with-even-more-interesting-snippet-dirs): Add
debug declaration.
(yas--collect-menu-items): New function.
(test-yas-define-menu): Use it to become keymap format agnostic.
* yasnippet.el (yas--delete-from-keymap): This function deletes entries
created by `yas--update-template-menu', which are always list elements.
Skip other types of keymap elements.
(yas--define-menu-1): Create a keymap with a vector element instead of a
list with gensym symbol binding list.
