The `pass.withExtensions`-function uses `buildEnv` to create a
derivation which contains a `pass`-package and a list of extensions for
it.
However, this function always uses the `pass`-attribute for `buildEnv` which
will break e.g. `passmenu` or `pass show -c` on desktops using Wayland (and
`pass-wayland.withExtensions`) since the default `pass`-package without
support for Wayland's clipboard is used.
This patch replaces the `pass`-attribute in the derivation with
`pass-wayland` to work around this issue.
