bug#27791: [PATCH] gnu: Add passmenu

[Jelle Licht]

In the end, I simply added dmenu to the list of `inputs' and replaced my
calls to `wrap-program' with a `substitute*' call. Pushed as 177475cfb5
to master.

Someone wanting to make use of an alternative to dmenu could just
inherit from `password-store' in order to override the relevant inputs
and/or phases. The closure size of password-store went from ~421MB to
~440MB, but as it is not a dependency of any non-password-store related
items, this should not be a big problem.

Thanks again for the guidance and reminders.
