waffle: add cmake-native to DEPENDS

waffle currently requires cmake-native because it has the following lines
in git/src/waffle/meson.build.

  if meson.version().version_compare('>= 0.50')
    cmake = import('cmake')

In case of 'wayland' not being in DISTRO_FEATURES, we will get the
following error at do_configure.

  | ../git/src/waffle/meson.build:233:8: ERROR: Unable to find cmake

So explictly add 'cmake-native' to DEPENDS to solve this problem.
