bug#4471: menu-bar menu is undefined

bug#4471: menu-bar menu is undefined

[Juri Linkov]

Some menu-bar's menus fail to open in non-toolkit X builds.

For instance, when I click on the "Buffer-Menu" menu-bar's item,
it signals the error:

  <menu-bar> <Buffer-menu-mode> <nil> is undefined

However, with the following patch it displays the menu correctly:

IIUC this is a correct way to fix it, indeed.
OTOH it would be better to make the non-toolkit code accept the same
keymaps as accepted by the toolkit code.

I've checked in a change to keyboard.c, allowing the non-toolkit code to
handle keymaps with no prompt strings.
