Restrict appnope dependency to darwin (#497)

This helps linux distro packagers, as distro
packaging needs to include -all- dependencies.
Restricting appnope to only be required on darwin
means that downstream packagers no longer have to
patch out the dependency and calls to appnope.

This should have no effect on macOS, and should be
basically unnoticeable to anyone who isn't doing
distro packaging.
